How to calculate the maximum capacity of the warehouse?

I think the simplest way to calculate the maximum storage capacity of a warehouse is to calculate according to the number of pallets, that is, to calculate how many pallets can be stored in a warehouse first, and then how many products can be stored in each pallet, so as to estimate how many products can be stored in a warehouse. (When calculating the maximum number of pallets, 85% of the maximum number of pallets can be estimated on the basis of theoretical calculation, because sometimes a ranking may not be full due to the limitation of product types, which mainly depends on the design of the ranking. )
