What volume of water is placed in a rectangular pool if its length is 5 meters, width is 3 meters, and depth is 1 meter?

What volume of water is placed in a rectangular pool if its length is 5 meters, width is 3 meters, and depth is 1 meter? How many square meters of tiles do you need to tile the bottom and walls of the pool?

The solution of the problem:

1) The volume of water will be equal to the volume of the pool. Since the pool is rectangular, its volume is:

V = abc = 5 * 3 * 1 = 15 (m3).

2) Find out how many meters of facing tiles are needed for a pool of this size:

5 * 3 = 15 (m2) – the bottom of the pool.

3 * 1 * 2 pieces = 6 (m2) – smaller pool walls.

5 m * 1 * 2 pieces = 10 (m2) – large pool walls.

15 + 6 + 10 = 31 (m2) – total pool area.

Answer: the pool holds 15 m3 of water; 31 m2 need tiles for the bottom and walls of the pool.
