Question

How much pressure does a box whose sides are 1.44 m long each exert on the ground due to gravity?Assume that the box has a mass of 17.3 kg. HINT: Look at the definition of pressure - what force is doing the "pushing?" What's the area?

Answer 1

Pressure = Force / area

m= mass = 17.3 kg

g= gravity = 9.8 m/s^2

Force = m * g = 17.3 kg * 9.8 m/s^2 = 169.54 N

P = F / A

A = area = 1.44^2 = 2.0736 m^2

P = 169.54 N/ 2.0736 m^2 = 81.76 Pa
