Pressure is the force per unit area.
This means that the pressure a solid object exerts on another solid surface is its weight in newtons divided by its area in square metres.
Pressure can be determined using the following equation.
A cube-shaped box of mass is sitting on a level table. If the length of each edge of the box is , calculate the pressure the box exerts on the table.
First calculate the weight of the box.
Then calculate the area of the box in contact with the table.
Area of box in contact with table
Now calculate the pressure.
