The pool was shaped like a rectangular parallelepiped measuring 10 meters 5 meters and 2 meters

The pool was shaped like a rectangular parallelepiped measuring 10 meters 5 meters and 2 meters long was filled with 1 quarter of water to find the volume of water.

Let’s calculate how many cubic meters the volume of a given pool, which has the shape of a geometric figure, namely a rectangular parallelepiped, is equal to, if we know from the terms of this assignment that its measurements are equal to five meters, ten meters and two meters:

5 * 10 * 2 = 100.

Let us calculate how many cubic meters the volume of a given pool, which was filled with water, is equal to, if we know from the condition of the problem that there is only 1/4 of it in water:

100 * 1/4 = 25.

Answer: The amount of water is 25 m3.
