Question

A solid concrete block weighs 169 N and is resting on the ground. The blocks dimensions are 0.400 m x 0.200 m x 0.100 m. A number of identical blocks are stacked on this one. What is the smallest number of whole blocks that can be stacked so that their weight creates a pressure of at least 2 atmospheres on the ground beneath the first block

Answer 1

so you would take the atmospheric pressure, times that by two to get the total atmospheric pressure, then you would divide that by the weight to get the total number of blocks, then round that DOWN to the nearest whole number
