The length of a rectangular aquarium is 90cm, the width is 2/3 of the length, and the height is 5/6 of the width.

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

a = 90 cm.
b =?, but is 2/3 of a.
c =? = 5/6 of b.
V =?.
1) Find the width by performing the action:
b = 90: 3 * 2 = 30 * 2 = 60 cm.
2) Calculate the height:
c = 60: 6 * 5 = 10 * 5 = 50 cm.
3) The aquarium has the shape of a rectangular parallelepiped, the volume of which is calculated by the formula:
V = a * b * c = 90 * 60 * 50 = 5400 * 50 = 270,000 cm³.
Since 1 liter = 1000 cm³, the volume of the aquarium is therefore 270 liters.
