16. A solid cube of metal is at rest on horizontal ground.
The cube has sides of length 10 cm.
(a) Find the area of one of the faces of the cube. [1]
(b)
The cube has a mass of 0·8 kg.
A mass of 1 kg has a weight of approximately 10 newtons.
Calculate the approximate weight of the cube. [1]
(c)
| \(\text{Pressure} = \dfrac{\text{Force}}{\text{Area}}\) |
Use the given formula and your answers to (a) and (b) to find the pressure made by the cube on the ground.
Give your answer as a decimal. [2]
