Question

A brick is 30 cm long ,10 cm wide and 10 cm thick. It weighs 27 N and is lying on the
ground. Find the pressure exerted by the brick on the ground.

Answer 1

If the brick is kept by it's length.

Then ,

the base area = 30cm = 0.3m

and force = 24N

Hence, the pressure = 24/0.3 = 80pa.

(as pressure = force/ area)

Similarly,

When it's kept by it's width

then, pressure = 24 / 0.1 = 240pa

and this would the same pressure when it's kept by it's thickness as both are same.
