The volume of the aquarium is 120,000 cm3. Find the height of the aquarium if its length is 60cm and width is 40cm.

Based on the conditions of the task, the aquarium has the shape of a rectangular parallelepiped, each face of which is represented by a rectangle.

Its volume is calculated by the formula:

V = a * b * c.

Provided that V of the aquarium is 120,000 cm³, and its width = 40 cm, length = 60 cm, we express the height:

c = V: a: b = 120,000: 40: 60 = 3000: 60 = 50 cm.
