There is a cabinet weighing 80 kg on the floor. how much pressure does it produce on the floor if the total area is 4500 cm ^ 2

Answer: 1777.78 Pa.
Explanation of the solution to the problem: to solve this problem, you must use the formula:
p = F / S, p – pressure in Pa, F – force acting per unit surface area, in N, S – support area in m ^ 2.
F = m * g, where m is the mass of the body, g is the acceleration of gravity, g = 10 m / s ^ 2.
First, it is necessary to translate the data in the condition of the problem, the numerical values into the SI system: S = 4500 cm ^ 2 = 0.45 m ^ 2.
Substitute the values into the formula: p = (m * g) / S = (80 * 10) / 0.45 = 1777.78 Pa.
