20 feet * 12 feet * 5 feet
= 20 * 12 * 5 feet ^3
= 1200 feet^3
1200 feet^3 / (30 feet^3 / minute)
= (1200 / 30) minutes
= (120 / 3) minutes
= 40 minutes
= 20 * 12 * 5 feet ^3
= 1200 feet^3
1200 feet^3 / (30 feet^3 / minute)
= (1200 / 30) minutes
= (120 / 3) minutes
= 40 minutes
The given dimensions of the rectangular swimming pool are =
Length = 20 feet
Width = 12 feet
Height upto which the water should be filled up = 5 feet
So, the total volume of water needed to fill the pool will be =
[tex]20\times12\times5=1200[/tex] cubic feet
The water is pumped at a speed of = 30 cubic feet per minute.
So, to fill 1200 cubic feet, the time taken will be = [tex]\frac{1200}{30} =40[/tex]
Hence, it will take 40 minutes to fill the pool.
