Question

A rectangular swimming pool is 20 ft long 15 feet wide,and 6 feet deep. How much water is needed to fill the pool completely ?

Answer 1

Answer: 1,800 ft.³

Step-by-step explanation: To find out how much water is needed to fill the pool, we need to find the volume of the pool. It's also important to understand that the swimming pool is a rectangular prism so we are finding the volume of a rectangular prism.

To find the volume of the pool, we use the formula shown.

Volume = length × width × height

Since the length of the pool is 20 feet, the width is 15 feet, and the depth or height is 6 feet we can plug this information into the formula.

Volume = (20 feet) (15 feet) (6 feet) = 1,800 ft.³

Therefore, it will take 1,800 cubic feet of water to fill the pool.
