Density of material = 10000kg/m
Density =mass/ volume
mass of cube = volume* density
volume of cube = cube of side
in SI system, volume of cube= 0.000008
mass f cube=0.08
weight of cube=mg=0.8= force acting on table due to weight of body
As we know pressure =force/area
Area of bottom of cube= 0.0004
pressure=2000 N/m2
