| Use: \[\text{Pressure} = \frac{\text{Force (N)}}{\text{Area (cm}^2\text{)}}\] |
The base of a filing cabinet is a rectangle. It measures 45 cm by 60 cm.
The whole of the base is in contact with the horizontal ground.
(a) The empty filing cabinet exerts a force of 675 N on the ground.
What is the pressure exerted on the ground by the empty filing cabinet?
Give your answer in N/cm2. [2]
