Question

A metallic cuboid of mass 15 kg and dimensions 10 x 15 x 5 is placed on the ground which exerts pressure on its surface .What is the minimum pressure which the metallic cuboid exerts on the ground ?

Answer 1

Mass of the cuboid=15 kg
Dimensions of the cuboid=10*15*5m (if dimensions are in m)
Maximum area occupied by the cuboid= 10*15
=150m^2
(we take the maximum area because larger the area, lesser the pressure)
Pressure=v/a
=750/150
=5kg/m^2

The minimum pressure exerted by the cuboid is 5kg/m^2
