3. The external length, width and height of an open rectangular container are 41 cm, 21 cm and 15.5 cm respectively.

The thickness of the materials making the container is 5mm. If the container has 8 litres of water, calculate the internal height above the water level. (4 marks)

Internal Dimensions :40,20, and 15

Volume unoccupied = 40 x 20 x 15 = 8000

= 4000

Height above water level = 4000/40 x 20 = 5cm
