Explanation:
we know that, pressure(p)=Force/area
force=mg
force=30*9.8
force=294 N
as we know that 2 opposite sides of a cuboid have same area, so one value of pressure is same for 2 opposite sides
the dimensions are given in cm, so first convert them into m
pressure exerted by block from it's 2 sides having area 0.30*0.20 m²
p=F/a
p=294/0.06 =4900 Pa
pressure exerted by block from it's 2 sides having area 0.30*0.15 m²
p=F/a
p=294/0.045=6533.34 Pa
pressure exerted by block from it's side having area 0.15*0.20 m²
p=F/a
p=294/0.03= 9800 Pa
