A cube of wood exerts a pressure of 2 pa. When it is placed on a floor. What is the force by the cube if its surface is 5 cm²

Pressure exerted by the wooden cube = 2 Pa

Surface area of cube = 5 cm² = 0.0005 m²

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Formula of Pressure:

P → Pressure

F → Force

A → Surface Area

By substituting values in the formula, we get:

Force applied by the cube on the floor = 1 mN
