A half-filled rectangular tank has 30,000 cm water. If its base is 750 cm, what is the height of the tank?

Height = 80 cm

Explanation:

Base area = 750 cm

Volume of water = 30,000 cm³

Since the tank is half-filled with water, it's volume is twice the amount of water.

Volume = 30,000 * 2 = 60,000 cm³

To find the height of tank;

Mathematically, the volume of a cylinder is given by the formula;

Volume = base area * height

Substituting into the formula, we have;

60,000 = 750 * height

Height = 60000/750

Height = 80 cm
