A rectangular tank with a base area of 600 cm2 and a height of 33 cm is filled with water to a height of 18 cm. How many liters of water are needed to fill the tank completely?

Answer 1

Hello, Zunairah,

The total volume of the rectangular tank is the base area times the height:

(600 cm²)*(33 cm) = 19800 cm³

The volume taken by the water is the base area times the water height:

(600 cm²)*(18 cm) = 10800 cm³

The difference of these two values is the empty volume:

(19800 cm³) - (10800 cm³) = 9000 cm³, the empty volume.

1 liter = 1000 cm³

(9000 cm³) = (1 liter/1000 cm³) = 9 liters

We need 9 liters to fill the tank.
