Cuboid and cube

Cuboid is a clever little boy. He lives in an ancient tribe called "Mathematical Wood sharky", and everything here is as beautiful as heaven. The elders said that it was because their ancestors were cared for by the goddess of nature, who always appeared in their tribe from time to time. Every time, she only saw a predestined relationship. If this predestined friend can pass her test, she will satisfy a reasonable wish of this predestined friend.

The cuboid is the most spiritual boy in "Two Wonders of Mathematical Musha" and the most likely person to become the goddess of nature. Cuboid doesn't agree with this, because he doesn't believe this legend.

One day, the cuboid went to play by the river, and there were already partners playing by the river, such as triangles, squares, circles and so on. . . Cuboid saw them there and turned away. Because cuboid doesn't like playing with unintelligent children and the tribe belongs to him, he always plays by himself. Hardly had he taken two steps when he heard Triangle calling for help. It turns out that the parallelogram fell into the river, and the water was not deep, but the parallelogram could not swim. The other children were frightened and ran to the shore, but they were afraid to get into the water. Cuboid saw that no one dared to walk, and suddenly wanted to jump into the river for fear that the parallelogram was in danger. At this moment, he suddenly remembered that he couldn't swim very well, but it was too late, cuboid.

One minute, two minutes, three minutes. . . . . . For ten minutes, neither the cuboid nor the parallelogram surfaced again.

All my friends thought they were dead and cried sadly. Suddenly, the cuboid rushed out of the water holding the parallelogram, and the cuboid saved the parallelogram. Everyone thanked the cuboid. The cuboid said nothing, but walked away.

The cuboid sits on the grassland and watches the scenery, and the goddess of nature appears. She is as beautiful as people say. The goddess of nature said, "cuboid, you have passed my test." Tell me, what is your wish? "

The cuboid said, "I don't know what you said. I'm not interested in knowing what test I passed." I'm not interested in telling you what I want. "

The goddess of nature has never met such a child with personality.

The goddess of nature said, "since you don't say anything, I'll make my own decision for you."

The cuboid said, "Suit yourself. I won't thank you anyway. "

The goddess of nature knew that the cuboid played alone and had no partners, so she created a cube. Cubes are as smart as cuboids. They are very similar to cuboids and have many common features. Cuboid likes this new partner very much.

The cuboid said to the goddess of nature; "I like cubes very much. They have many similarities with me, like my shadow, but they are completely different from me and have their own personality. "

The goddess of nature said, "I'm glad you like it." In fact, the cube is another special you. You are more special than yourself. In the future, you will naturally understand. "

2. Give some math stories and knowledge. Be brief.

One day, the Tang Priest told his disciples Wukong, Bajie and Friar Sand to go to Huaguoshan to pick peaches. Soon, the three disciples came back happily after picking peaches. Tang Priest and his disciples asked: How many peaches did each of you pick? Bajie said with a silly smile, Master, let me test you. Each of us took the same amount of money. There are less than 65,438+000 peaches in my basket. If you count three plots, there is still 1 left. Do you calculate how many peaches each of us picked? Friar Sand said mysteriously, Master, I will test you, too. If there are four peaches in my basket, there is 1 left in the end. Calculate, how many peaches did we each pick? Wukong smiled and said, Master, I'll test you, too. If you count five peaches in my basket, there is 1 left in the end. Calculate, how much will each of us choose? 2 Digital Fun Association Su Dongpo, a great poet in the Song Dynasty, went to Beijing with several schoolmates to take the exam when he was young. When they arrived at the examination center, it was too late. The examiner said, "I made an association. If you are right, I will let you into the examination room." The examiner's first association is: a single leaf in a boat, two or three students, four oars and five sails, passing through six beaches and seven bays, but it's too late. Su Dongpo has been tested three times and twice, and I must get a correct answer today. Examiners and Su Dongpo both embedded ten numbers from one to ten in couplets, which vividly described the hardships and assiduousness of literati. Learning mathematics with three wrong decimal points not only requires correct thinking, but also can't make mistakes in the specific problem-solving process. An old woman living on a pension in Chicago, USA, went home after a minor operation in the hospital. Two weeks later, she received a bill from the hospital for $63,440. When she saw such a huge number, she couldn't help being surprised. She had a heart attack and fell to the ground dead. Later, someone checked with the hospital, and it turned out that the computer misplaced the decimal point, but in fact she only had to pay $63.44. A wrong decimal point actually killed a person. As Newton said, "in mathematics, even the smallest error can't be made."

I have to cut the apple, but I can't cut it into pieces. Xiaomi's father wants each apple to be cut into three pieces at most. This has become another topic: divide five apples equally among six children, and each apple is not allowed to be cut into more than three pieces.

How did Xiaomi's father do it?

Ma Xiao Hu cooked chicken

During the Spring Festival, Xiao Mahu, a professional chicken farmer, stood in the yard, counted the total number of chickens, decided to stay and gave 1/2 to the nursing home. After he sent the chickens away, he heard the chickens crowing in the room, only to know that there were 10 chickens missing. So I counted the chickens inside and outside the room again, and there was nothing wrong, no more, no less, just 1/2 left. Little careless and strange. What's the problem? Do you know how many chickens Xiao Mahu counted in the yard? "This article is organized by the first model essay network, and the copyright belongs to the original author and the original source. 』

4. Write a math story with the math knowledge you have learned, such as the dialogue between master and apprentice.

Interesting math story editor: There are many interesting stories in Li's math kingdom, which will make you fondle it! 1. Ingeniously measure the height of the pyramids. The pyramids are famous Egyptian buildings, especially pyramid of khufu. The entire pyramid used 2.3 million stones, and it took 654.38 million slaves 30 years to build this building. After the completion of the pyramid, the king asked another question, how high is the pyramid? No one can answer this question. The king was furious and threw all the scholars who couldn't answer into the Nile. When the king tried to kill another scholar, the famous scholar tallis appeared and ordered the executioner to stop. The king said, "Can you know the height of the pyramid?" Tallis said, "Yes, Your Majesty." The king said, "Then how high is it?" Tallis calmly replied: "147 meters." The king asked, "Don't talk nonsense. How did you measure it? " Tallis said, "I can show it to you tomorrow." The next day, when the sun was shining, tallis came to the bottom of the pyramid with only a stick. King Qi sneered, "You want to cheat me with this broken stick? If you can't measure it today, you will be thrown into the Nile! " Tallis replied unhurriedly, "If I can't measure it, it's not too late for your majesty to throw me into the Nile." Then, tallis began to measure, and finally, the king had to accept that his measurement was reasonable. Children, do you know how to measure in tallis? 2. When did the snail climb the well? A snail accidentally fell into a dry well. It lay at the bottom of the well and began to cry. A toad crawled over and whispered to the snail, "don't cry, little brother!" It's no use crying. The shaft wall is too high. If you fall here, you can only live here. I have been here for many years, and I haven't seen the sun for a long time, let alone want to eat swan meat! " The snail looked at the old and ugly toad and thought, "What a beautiful world outside the well! I can never live in a dark and cold well like it! " The snail said to the toad, "Uncle toad, I can't live here. I have to climb up! "! How deep is this well? ""Ha ha ha ..., are you kidding! The depth of this well is10m. How can you climb up with such a heavy shell at a young age? " "I am not afraid of suffering, not afraid of being tired. I can always climb out after a while every day! " The next day, the snail ate and drank enough and began to climb the wall. It kept climbing and finally climbed 5 meters at night. The snail was very happy and thought, "At this rate, I can climb up tomorrow night." Thinking about it, it fell asleep unconsciously. In the morning, the snail was awakened by a purr. At first glance, it turned out that Uncle Tu was still sleeping. It was surprised: "How come I am so close to the bottom of the well?" It turned out that this snail slipped 4 meters from the borehole wall after falling asleep. The snail sighed, gritted his teeth and began to climb again. At night, it climbed another 5 meters, but at night the snail slipped another 4 meters. Climb and climb, and finally the strong snail climbed up the well platform. Can you guess how many days it will take a snail to climb the drilling platform?

3. Controversy between "0" and "1" In the mysterious mathematical kingdom, the two "minor figures" 0 and "1" are often disputed because of who is important. Look! Today, these two little enemies meet in a narrow way, and they have launched another war of words. The thin man "1" spoke first: "Hum! Fat' 0', what's so great about you? Just like 100, what's the use of you two fat' 0' without my thin'1'?" Fat man "0" is not convinced: "Don't be overbearing in front of me. Think about it. Without me, where are you going to find other numbers 100? " "hey!" "1" is not to be outdone. "If you are arrogant again, you are nothing. Look! 1+0' is not equal to myself. What's your use? ""go! The result of'1* 0' is not me, and your'1'is also useless! "'0' is tit for tat." You ... "1" paused and improvised. " Anyway, your' 0' is nothing! ""This is your lack of knowledge. " "0" said unhurriedly, "You see, in daily life, the temperature is 0 degrees. Is there no temperature? For another example, without my starting point on the ruler, how can there be'1'?" "No matter how you compare, you can only do the middle number or mantissa, such as 1037, 1307, and you can never lead." 1 "said confidently. Hearing this, "0" said more confidently: "This may be, for example, 0. 1, what can you do without my" 0 "to occupy it?" Seeing the fat man "0" and the thin man "1" all blushed, and no one would let anyone, and other people watching were very anxious. At this time, "9" had a brainwave and made a gesture of pause: "You two stop arguing. Look at you, which number is greater than'1'and' 0'? " "This ..." The fat man "0" and the thin man "1" were speechless. At this time, "9" said quietly: "1"and "0", in fact, as long as you stand together, aren't you older than me? "1" and "0" looked at each other, and it took a long time to scratch their heads and laugh. " That's right! The power of unity is the most important! ""No.9 "said earnestly. I found it for you. Choose for yourself.

5. A mathematical fairy tale that can explain a formula or concept and be touched in the first grade.

The first chapter is the rich graphic world 1. Prisms include straight prisms and oblique prisms.

2. Graphics are composed of points, lines and surfaces. 3. Faces intersect to get lines, and lines intersect to get points.

4. Point to line, opposite the line, facing the body. 5. In a prism, the intersection of any two adjacent faces is called an edge, and the intersection of two adjacent sides is called a side. All sides of a prism are equal in length.

The upper and lower bottom surfaces of the prism have the same shape, and the side surfaces are rectangular. 6. Cut a cuboid with a plane, and the section is called a section.

7. Call it front view, left view and top view. 8. A plane figure is a closed figure composed of some line segments that are not on the same straight line.

9. A graph consisting of an arc and two radii passing through the end of the arc is called a fan. Chapter II Rational Numbers and Their Operation 1. Rational number: integer positive number, 0, negative number; Irrational number: the fraction is positive and the negative number is 2. Numbers greater than 0 are called positive numbers, which are represented by the symbol+(pronounced as positive numbers).

3. A number less than 0 is called a negative number, which is represented by the symbol-(pronounced negative). 4.0 is neither positive nor negative.

5. Draw a horizontal straight line, take a point on the straight line to represent 0 (called the origin), choose a certain length as the unit length, and specify the right direction on the straight line as the positive direction to get the number axis. 6. Any rational number can be represented by a point on the number axis.

7. If two numbers are only different in sign, then we call one of them the inverse of the other number, which is also called the inverse of each other. The antonym of 0 is 0.

8. The number represented by two points on the number axis is always larger on the right than on the left. 9. Positive numbers are greater than 0, negative numbers are less than 0, and positive numbers are greater than negative numbers.

10. The distance between the point corresponding to a number and the origin on the number axis is called the absolute value of the number. 1 1. The absolute value of a positive number is itself; The absolute value of a negative number is its reciprocal; The absolute value of 0 is 0.

12. Comparing two negative numbers, the larger absolute value is smaller. 13. Add two numbers with the same symbol, take the same symbol, and add the absolute values; Two numbers with different signs are added, and the sum is 0 when the absolute values are equal; When the absolute values are not equal, take the sign of the number with larger absolute value and subtract the number with smaller absolute value from the number with larger absolute value; Add a number to 0 and you still get the number.

14. Subtracting a number is equal to adding the reciprocal of this number. 15. When two numbers are multiplied, the sign of the same symbol is negative, and the absolute value is multiplied.

Multiply any number by 0, and the product is still 0. 16. Two rational numbers whose product is 1 are reciprocal.

17. Divide two rational numbers, the same sign is positive and the different sign is negative, and divide by the absolute value. Divide 0 by any number except 0 to get 0.

0 cannot be partitioned. 18. Dividing by a number is equal to multiplying the reciprocal of this number.

19. the operation of finding the product of n identity factors a is called power, the result of power is called power, a is called base, and n is called exponent. 20. Calculate the power first, then multiply and divide, and finally add and subtract; If there are brackets, count them first.

Chapter III Letters represent the number 1. The formula of numbers or letters connected by operation symbols is called algebraic expression, and a single number or letter is also an algebraic expression. 2. Items with the same letter and the same letter index are called similar items.

Merging similar items into one item is called merging similar items. 3. When merging similar items, we add up the coefficients of similar items, and the indexes of letters and letters remain unchanged.

There is a "+"before the bracket. After removing the brackets and the "+"sign in front of them, the symbols of the items in the original brackets remain unchanged; There is a "-"before the brackets. After removing the brackets and the "-"sign in front of them, the symbols of the original brackets will change. Chapter iv floor plan and its positional relationship 1. A line segment has two endpoints; Extending a line segment infinitely in one direction forms a ray, which has an endpoint; A straight line is formed by an infinite extension of a line segment in two directions, and the straight line has no end points.

There is a straight line after two o'clock. 3. In the connection between two points, the line segment is the shortest.

The length of the line segment between two points is called the distance between these two points. 4. An angle is a graph composed of two rays with a common endpoint, and the common endpoint of the two rays is the vertex of the angle.

5. An angle can also be regarded as a ray rotating around its endpoint. 6. A ray drawn from the vertex of an angle divides the angle into two equal angles. This ray is called the bisector of the angle.

7. We usually use "∨" to indicate parallelism. After passing a point outside the straight line, there is one and only one straight line parallel to this straight line; If both lines are parallel to the third line, then the two lines are parallel to each other; Two straight lines intersect and there is only one intersection.

8. We usually use ⊥. In the plane, there is one and only one straight line perpendicular to the known straight line; Of all the line segments connecting the outer point and the point on the line, the vertical line segment is the shortest.

9. If two straight lines intersect at right angles, they are perpendicular to each other. 10. The intersection of two vertical lines is called vertical foot.

Chapter 5: One-dimensional linear equation 1. In an equation, there is only one unknown X (element), and the exponent of the unknown X is 1 (degree). Such an equation is called a one-dimensional linear equation. 2. Adding (or subtracting) the same algebraic expression on both sides of the equation at the same time, the result is still an equation.

3. Both sides of the equation are multiplied by the same number at the same time (or divided by the same number that is not 0), and the result is still an equation. Chapter VI Data in Life 1. Use circles and sectors to represent the relationship between the whole and the parts, that is, use circles to represent the whole. Each sector in the circle represents a different part of the whole, and the size of the sector reflects the percentage of the part in the whole. This kind of statistical chart is called departmental statistical chart.

2. In the sector statistical chart, the percentage of each part in the whole is equal to the ratio of the central angle of the sector corresponding to this part to 360. 3. The pie chart can clearly show the percentage of each part in the total.

Bar chart can clearly show the specific figures of each project. 5. The broken line statistical chart can clearly reflect the changes of things.

Chapter VII Possibility 1. In life, there are some things that we can be sure will happen in advance. These things are called inevitable events. Some things we can make sure in advance will not happen. These things are called impossible events.

Inevitable events and impossible events are certain. There are also many things that we can't determine in advance whether it will happen, which is called uncertainty.

6. Who can tell a math story of senior one? The homework assigned by the teacher is a bit abnormal ~ ~ ~ Oh.

I don't know how many words your story needs, so I chose one that is not too long. If it is too long, it can be shortened.

1796 One day, at the University of G? ttingen in Germany, a 19-year-old young man was extremely talented in mathematics. After dinner, he began to do three routine math problems assigned to him by his tutor.

The first two questions were successfully completed in two hours. The third question is written on another small piece of paper: it is required to draw a regular 17 polygon with only a compass and an uncalibrated ruler.

He felt very tired. A minute passed, and the third question made no progress. Young people rack their brains, only to find that all the mathematics knowledge they have learned doesn't seem to help solve problems.

Difficulties aroused his fighting spirit: I must do it! He picked up the compass and ruler, and while thinking, he drew on the paper, trying to find the answer with some unconventional ideas.

When the dawn appeared, the young man breathed a sigh of relief, and he finally finished the difficult problem.

Seeing the tutor, the young people felt guilty and blamed themselves. He said to his tutor, "The third question you assigned me, I worked all night and failed to live up to your cultivation ..."

The tutor looked at the students' homework and was shocked at once. He said to the young man in a trembling voice, "Did you make this yourself?" The young man looked at the tutor doubtfully and replied, "I did it." However, I spent the whole night. "

The tutor asked him to sit down, took out the compass and ruler, spread the paper on the desk, and asked him to make another regular 17 polygon in front of him.

The youth quickly made a regular 17 polygon. The tutor excitedly said to him, "Do you know? You solved a math unsolved case with a history of more than two thousand years! Archimedes didn't solve it, Newton didn't solve it, you solved it in one night. You are a genius! "

It turns out that my tutor has been trying to solve this problem. That day, because of a mistake, he handed the note with this topic to the students. This young man is Gauss, the prince of mathematics.

7. A 300-word interesting math story in Grade One.

Once upon a time, there was an old man. On his deathbed, his three sons gathered at the bedside.

He said to his sons, "I have prepared seventeen horses for you, and I will give them to three people." When the horse was divided, the boss contributed the most, with half of it; The second child, one third; The third is the youngest, so you can take one ninth of the total. "

After barely saying these words, the old man died. When the three brothers executed their wills, they agreed that these horses were their father's favorite things before his death, and they must never divide any of them into several pieces. But the will must be completely obeyed. What should we do?

As it happens, their old uncle came on horseback. After listening to the story, he raised his eyebrows and said, "I'll share it."

Guess, how did the old uncle divide the horse?

Because everyone wants an integer horse, according to the will, when dividing horses, the number of horses should be the common multiple of three denominators. The least common multiple of denominators 2, 3 and 9 is 18, so the total number of horses separated by horses should be a multiple of 18. The old man left his sons 17 horses, and the old uncle temporarily borrowed a horse he brought to make up the number. * * * There are 18 horses participating in the distribution.

Ready, the old uncle began to read and execute the will:

"... when dividing horses, the boss contributed the most, accounting for half ..." After reading this, the old uncle counted nine horses and asked the boss to take them:

Second, one-third of the total ... "After reading this, the old uncle counted six horses and let the second one lead him:

"The third is the smallest. You, take one-ninth of the total. " After reading the last sentence, the old man counted two horses and let the third horse lead him:

The sum of the horses divided by the three younger generations happened to be left by the father 17 horses;

9+6+2= 17。

There are 18 horses in the racecourse, and now there is only one left. Of course, my uncle borrowed it temporarily, and now it is still returned to its owner.

8. Math Story of Grade One.

1 Han Xin was a general in the Han Dynasty. When he was a child, he used his brains and was brilliant.

Legend has it that one day, two oil sellers in the street quarreled endlessly. Han Xin passing by just glanced at him out of curiosity.

He finally understood that the two men were partners in selling oil. Because of disagreement, they are going to divide the remaining ten catties of oil in the barrel equally and go their separate ways, arguing over the uneven distribution of oil. Han Xin looked at it carefully. They don't have a scale at hand, only a 3 kg oil gourd and a 7 kg crock.

They turned the oil drum upside down, but both sides were always dissatisfied, so they quarreled. Is there any way to accurately divide the oil? Han Xin faced two oil sellers and the oil drums, oil pots and oil gourds in front of him, thinking silently.

Suddenly my eyes lit up and I said loudly, "Stop arguing, you can split it equally without a scale!" " "Say that finish, he gave directions to the oil seller. According to Han Xin's method, they divided it again, and they were all satisfied.

Solution: First, wrap the oil gourd three times in a row, * * * 9 kg. After the 7 kg crock is filled, there are 2 kg left in the oil gourd. Then pour all 7 Jin of the crock into the oil drum, and then the oil drum is 8 Jin of oil.

Then pour all 2 Jin of oil in the oil gourd into the crock. Finally, fill the oil drum with an empty gourd (3 kg) and pour it into the crock.

In this way, the oil left in the oil drum and the oil in the crock are exactly 5 Jin. Both sides have their own points, and it happens that everyone's income is exactly the same.

Hou, the master of crosstalk, has a good personal relationship with the famous mathematician Hua. One day, two masters were drinking and chatting. You came and went, chatting happily. Hou Wenhua asked, "Under what circumstances 2+3 equals 4?" China can't understand at the moment. Just as he was deep in thought, Hou Linbao said, "As long as the mathematician is drunk, won't the problem be solved?" Hua couldn't help laughing: "What a humorous master, trying to make fun of me.

"He said to Hou," please buy a catty of orange juice and a packet of fried rice with flowers in the street to take away.

A catty of orange juice is 44 cents, and I only give you 44 cents here. I won't buy the expensive ones, and I won't do the missing ones! Hou came back soon after accepting the task. He gave Hua a catty of orange juice and a packet of fried rice flowers. How did Hou Linbao finish the task? It turned out that Hou made a detour to ten grocery stores, each of which bought only one or two pieces, beat a catty of orange juice, and bought a packet of fried rice flowers with the remaining 40 cents.
