    Given:–

    • Mass = 75 kg
    • 280 cm² = 280/10000 m² = 28/1000 m²

    To be calculated:-

    Calculate the pressure exerted on a level ground.

    Formula used:–

    Pressure = Force/Area

    Solution:–

    First of all,

    We have to find out Force ;

    Force = m × g

    Force = 75 kg × 9.8 m/s²

    Force = 735 kg.m/s² [ 1 N = kg.m/s² ]

    Force = 735 N

    Now,

    Pressure = Force/Area

    Pressure = 735 / 28/1000

    Pressure = 735 × 1000 / 28

    Pressure = 735000 / 28

    Pressure = 26,250 Pascal
