A rectangular swimming pool is 8 ft deep. One side of the pool is 3.5 times longer than the other. The amount of water needed to fill the swimming pool is 4032 cubic feet. Find the dimensions of the pool.

Dimension of pools are length = 42 ft, width = 12 ft and depth = 8 ft that is 42ft * 12ft * 8 ft

Step-by-step explanation:

given that depth of pool = 8 ft

let say one side of pool that is width = x

so other side of pool that is lenght = 3.5x [ given ]

volume of rectangular swimming pool is same as amount of water required to fill the swimming pool = 4032 cubit ft

Volume of rectangular pool = length * width * depth of swimming pool

⇒ 4032 cubic ft = 3.5x * x * 8

⇒ 4032 / (3.5 * 8) = x²

⇒x² = 144

⇒x = √144 = 12

⇒3.5x = 12 * 3.5 = 42

hence dimension of pools are length = 42 ft, width = 12 ft and depth = 8 ft that is 42ft * 12ft * 8 ft
