What is the magnitude of the perpendicular force, if it exerts a pressure of $50,000 \mathrm{Pa}$ over an area of $0.125 {\mathrm{cm}}^2$?

A wooden block of dimensions $40 \mathrm{cm}\times 20 \mathrm{cm}\times 10 \mathrm{cm}$ is found to weigh $5 \mathrm{kg}$. Find the pressure exerted by the block on a tabletop, if it is allowed to lie on the tabletop with its sides $40 \mathrm{cm}\times 20 \mathrm{cm}$ $\left[\mathrm{Take} g=9.8 \mathrm{m} {\mathrm{s}}^{-2}\right]$.
