the mass of a brick is 2.5 kg. its dimensions are 10cmx5cmx2cm. find the pressure of the brick exerts on the ground if it is resting on a. 10cmx5cm base and b. 5cmx2cm base

Answer 1

Pressure = force / area

Force = mg = 2.5*9.81 N
a. Area = 10cm * 5 cm =0.10*0.05 m²
=0.005 m²

Pressure = 2.5*9.81/0.005=4905 Pa

Part b can be solved similarly.
