Question

A rectangular water tank measures 15 m x 6 m at top and is 10 m deep. It is full of water. If water is drawn out lowering the level by 1 metre, how much of water has been drawn out?

Accepted Answer

To find the volume of water drawn out, we calculate the volume of the upper 1 metre layer of the tank.

The length of the tank is 15 metres and the width is 6 metres. When the water level is lowered by 1 metre, the depth of the water removed is 1 metre.

Volume equals Length times Width times Depth.
Volume equals 15 times 6 times 1 which equals 90 cubic metres.

To convert cubic metres to litres, we use the standard conversion where 1 cubic metre equals 1,000 litres.
Total water drawn equals 90 times 1,000 which equals 90,000 litres.

Therefore, the correct option is B.

Answer
