# The volume of the pool is 800m3, the side of the base is 10m and 40m. How many square meters

The volume of the pool is 800m3, the side of the base is 10m and 40m. How many square meters of tiles were used for the lining of the pool?

Let’s calculate the area of the pool base. We multiply the length – 40 meters by the width – 10 meters:

10 * 40 = 400 m².

Find the height of the pool. We divide the volume by the area of the base:

800: 400 = 2 meters.

The pool height is 2 meters.

Find the area of the pool side faces:

2 * 10 = 20 m².

2 * 40 = 80 m².

Each face has two:

20 * 2 = 40 m².

80 * 2 = 160 m².

40 + 160 = 200 m².

Let’s add the base area:

200 + 400 = 600 m².

The entire pool was tiled over 600 m².

Answer: 600 m² was used to tile the entire pool.
