Question:
A swimming pool is 260 m long and 140 m wide. If 54600 cubic metres of water is pumped into it, find the height of the water level in it.
Solution:
Length of the pool $=260 \mathrm{~m}$
Width of the pool $=140 \mathrm{~m}$
Volume of water in the pool $=54600$ cubic metres
$\therefore$ Height of water $=\frac{\text { volume }}{\text { length } \times \text { width }}=\frac{54600}{260 \times 140}=1.5$ metres
