Question

A swimming pool is 30m long and 15m wide. How many kilolitres of water must be pumped into it so as to raise the level of water by 4m?(1000cm3=1 litre)

Answer 1

required water=30×15×4=1800m^3

Answer 2

1.8 liters of water must be pumped into it so as to raise the level of water by 4m

Step-by-step explanation:

Length of pool = 30 m

Breadth of pool = 15 m

Height of water level = 4 m

Volume of water =$Length \times Breadth \times Height = 30 \times 15 \times 4=1800 cm^3$

1000 cubic cm = 1 liters

1 cubic cm = $\frac{1}{1000}$liters

1800 cubic cm $= \frac{1800}{1000}=1.8 liters$

Hence 1.8 liters of water must be pumped into it so as to raise the level of water by 4m
