What is the pressure on the ground produced by a box weighing 80 kg and a bottom area of 400 cm2?

Initial data: m (box weight) = 80 kg; S (box bottom area) = 400 cm2.

Constants: g (acceleration due to gravity) = 10 m / s2.

SI system: S = 400 cm2 = 400 * 10-4 m2 = 0.04 m2.

The pressure that this box will produce on the ground is determined by the formula: P = Fт / S = m * g / S.

Let’s calculate: P = 80 * 10 / 0.04 = 20,000 Pa or 20 kPa.

Answer: The box exerts a pressure of 20 kPa on the ground.
