A car weighing 4000 kg has a support area of 800 cm: cubic. What is the pressure and pressure of 15 kPa

m = 4000 kg.
S = 800 cm ^ 3 = 0.0008 m ^ 3.
g = 10 m / s ^ 2.
P -?
Pressure P is the ratio of the force F to the area S, on which this force acts: P = F / S.
The machine acts on the surface of the earth with gravity: F = m * g, where m is the mass of the car, g is the acceleration due to gravity.
P = m * g / S.
P = 4000 kg * 10 m / s ^ 2 / 0.0008 m ^ 3 = 50,000,000 Pa.
Answer: car pressure P = 50,000,000 Pa.
