Question

calculate the pressure exerted by a cube of mass 500g at each side of the cube is 50cm

Answer 1

mass 500kg=o.5×10=5N
side=0.5×0.5=0.25
pressure=force/area
5N/o.25=20pa

Answer 2

Side of cube = 5 m
vol. = 5×5×5 m^3
area of base = 5×5 m^2
= 25 m^2
weigh = 50 kg.
gravity = 10 m/s^2
weight = m×a
= 50×10
=500 N.
pressure = Force / Area
= 500/25
= 20 Pa.
