Question

A block with length of 1.5 m, height 0.5 m, width 1 m, and mass 300 kg lies on the table. Find the pressure exerted by the block on the table

Answer 1

Pressure = force/area

Force = mg= 3000N

Area= 2(lb+bh+hl)

=2(1.5×1+1×0.5+0.5×1.5)

=2(1.5+0.5+0.75)

=2(2.75)= 5.5

Pressure = 3000/5.5= 545.45N

Answer 2

I tried it in this way. Is it correct??
