| **The length of the rectangular aquarium is 90 cm, the width is 2/3 of the length, and the height is 5/6 of the width. Find the volume of the aquarium?**

1) Find the width of the aquarium.

90 * 2/3 = 180/3 = 60 (cm).

2) Find the height of the aquarium.

60 * 5/6 = 300/6 = 50 (cm).

3) Find the volume of the aquarium. The aquarium has the shape of a rectangular parallelepiped. The volume of a rectangular parallelepiped is equal to the product of its three dimensions. V = sbc.

90 * 60 * 50 = 270,000 (cm ^ 3) = 0.27 (m ^ 3).

Answer. 270,000 cm ^ 3 = 0.27m ^ 3.
