Question

A swimming pool is 40m long and 15m wide. Its shallow and deep ends are 1.5 m and 3m deep respectively. If the bottom of pool slopes uniformly, find the amount of water in litres required, find the amount of water in litres required to fill the pool

Answer 1

V=lwh
V=40*15*3/3
V=600cubic meter

Answer 2

Answer:

so we can consider the pool is in a shape of a cuboid + a half cuboid with same dimension  

so total volume = 3/2V = 3/2 x 40 x 1.5 x 15 = 1350 m³ = 1350000 L  (1 m³ = 1000 L)
