Question

A swimming pool is 18 m long and 8 m wide. Its deep and shallow ends are 2 m and 1.2 m respectively. Find the capacity of the pool, assuming that the bottom of the pool slopes uniformly. 

Answer 1

Length of pool = 18 m

Breadth of pool = 8 m

Height of one side = 2m

Height on second side = 1.2 m

∴ Volume of pool = 18 x 8 x `(( 2 + 1 . 2 ))/( 2 )` m³

= `( 18 xx 8 xx 3.2 )/( 2 )`

= 230.4 m³
