What is the depth of water in the tank shown if the volume of water is 4000 litres?
- 50 cm
- 80 cm
- 5 m
Explanation from PART66Online
4000 litres is 4 cubic metres, since 1 cubic metre holds 1000 litres. The tank's base is 4 m x 2 m = 8 square metres, so the depth of water is volume / base area = 4 / 8 = 0.5 m, which is 50 cm. The 5 m option treats 4000 litres as 40 cubic metres.

1 litre = 1000 cm^3 , 4000 litres = 4,000,000 cm^3 , Volume of water is 4m x 2m x depth, Change to cm 400 * 200 *
depth = 4,000,000, Therefore, depth = 4,000,000/(400*200) = 400/8 = 50 cm.
depth = 4,000,000, Therefore, depth = 4,000,000/(400*200) = 400/8 = 50 cm.
