Question

Each of the four sides of a swimming pool measures 9 meters. The pool is 5 meters deep. How much water will be needed to fill it completely?

Answer 1

9 * 9 * 5 = 405 cubic meters = 405,000 liters = 405,000,000 cubic centimeters

= 106,990 gallons

Answer 2

405 meters³

Explanation:

How much water requires is in reference to the volume required. The pool is in form of a cuboid.

The volume V of a cuboid is given as the product of the length l, the width w and the depth h of the cuboid.

In this instance, the length and width are the same at 9 meter and the depth is 5 meters hence the volume V

= 9 meters * 9 meters * 5 meters

= 405 meters³
