If the dimensions of a brick that weighs 25 N are 0.19 m x 0.07 m x 0.095 m, what pressure does the brick exert on the ground if it is resting on its largest face?

1 newton per square meter = 1 pascal of pressure.
The largest face of the brick is (0.19 x 0.095) = .01805 square meter
25N/0.01805 = 1,385 newtons per square meter = 1,385 pascal = 1.385 kPa

The pressure exerted by the brick on the ground is calculated using the formula P = A F ​ , where F is the weight and A is the area of the largest face. The pressure is approximately 1385.65 Pa or 1.386 kPa . This shows how force distributed over a larger area leads to lower pressure.
