Answer:
Size of Mariana's swimming pool would be 2933 cubic feet.
Step-by-step explanation:
Mariana's swimming pool holds water = 22,000 gallons
there are 7.5 gallons water per cubic foot,
Now we have to calculate the size of the swimming pool by unitary method.
∵ 7.5 gallons of water is contained = 1 cubic foot of pool
∴ 1 gallon of water will be contained in = cubic foot
∴ 22,000 gallons of water will be contained in =
= 2933 cubic feet
Size of Mariana's swimming pool would be 2933 cubic feet.
