Question

A swimming pool is 18m long and 8m wide. its shallow and deep ends are 1.2m and 2m deep respectively. If the bottom of the pool slopes uniformly, then the capacity of the pool is 230.4 $m^3$

• A. True
• B. False

Answer 1

The correct option is A

True

length of pool = 18m

width = 8 m

Area of cross section = 18 x 8 = 144 $m^2$

Height = $\frac{1.2+2}{2}=\frac{3.2}{2}m$

Volume = area of cross section x height

= 144 x $\frac{3.2}{2}$

= 230.4 $m^3$
