A swimming pool is 40m long and 15m wide. Its shallow and deep ends are 1.5 m and 3 m deep respectively. If the bottom of pool slopes uniformly. Find the amount of water in liters required to fill the pool.
Length (l) = 40m
Width (w) = 15m
Shallow end height = 1.5 m
Deep end height = 3m
So, To find the volume of the pool, we first find the area of trapezium ABCD and considering trapezium as base multiply it with width to find the volume.
= 90 m2
The volume of water to fill pool = Base area × height
Here height is the width of the pool (w)
⇒ Volume = 90 × 15
= 1350 m3
So, amount of water required to fill pool is 1350000 litres.
