The bottom of a box weighing 100 kg has an area of 0.04 m2, calculate the pressure that the box produces on the floor.

The pressure of the box on the floor is the ratio of the force with which the mass of the box will press on the floor to the value of the area of the bottom of the box.
P = F / S, where P is the pressure of the box on the floor (Pa); F is the force of pressure on the floor (F = Ft = m * g, where m is the mass of the box (m = 100 kg), g is the acceleration of gravity (we take g = 10 m / s ^ 2)), S is the area of the bottom of the box (S = 0.04 m ^ 2).
Let’s calculate the pressure of the box on the floor:
P = F / S = m * g / S = 100 * 10 / 0.04 = 25000 Pa = 25 kPa.
Answer: The pressure of the box on the floor is 25 kPa.
