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

  • physics -

    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.
