The pool has the shape of a rectangular parallelepiped, the length of which is 100 m, the width is 12 m, and the depth is 180 cm. Find the volume of water in the pool, if the water level in it is 30 cm below the upper edge?

1 action.
Find the depth of the pool filled with water. To do this, it is necessary to subtract the edge of the pool that is not filled with water.
180 – 30 = 150 cm = 1.5 m.
2 action.
Find the volume of water in the pool. To do this, the width must be multiplied by the height and by the length, since the pool has the shape of a rectangular parallelepiped.
100 * 12 * 1.5 = 3000 m3.
Answer: the volume of water in the pool is 3000 m3.
