Two meters high. Tell me about it.

Usage per 100 m = 100/[ (block length+mortar joint width) × (block width+mortar joint width) ]×( 1+ loss rate) For example, the specifications of retro floor tiles are 0.5×0.5M, the flat-fell seam width is 0.002M, and the loss rate is 0.002m.. The number of blocks required for 100 m2 is: 100 m2, and the dosage =100/[(0.5+0.002) × (0.5+0.002 )× (1+0.065438) is about 400. The unit price of PVC plastic board is 50.8 1 yuan per square meter, the shielding length and width are all 0.24M, the ceiling is 3M long and 4.5m wide, and the dosage is as follows: the dosage of ceiling board = (3-0.24) × (4.5-0.24) is about equal to 1 1.76 per square meter. The outer frame of the door is 2.7M long and 1.5M wide, so the material consumption is as follows: the material consumption of the door = 2.7× 1.5 = 4.05m2. 4. Usage of wallpaper: wallpaper usage = (height-shielding length) × (width-shielding width )× number of walls-door area-window area. The wall surface is calculated according to the net size area. Then the consumption is as follows: wallpaper consumption = [(2.5-0.24) × (5-0.24) ]× 4-2.8-3.6, which is about equal to more than 36.6 square meters. The total material cost of the decoration project is obtained by multiplying the decoration consumption of each part with their respective unit prices. Price source network, please check it yourself.
