Given parameters
Weight of the box = 120N
Area of the box = 12cm^2
Unknown
Pressure of the box on the floor = ?
Solution
Pressure is the fore exerted by a body per uint area
Pressure = force/area
We need to convert the area into m^2 from cm^2
10000cm^2 = 1m^2
12cm^2 = 12/1000 = 0.0012m^2
Pressure = 120/0.0012 = 100000N/m^2
