Question

An empty rectangular tank is 60 cm long by 50 cm wide. The tank is being filled with water flowing from a tap at a rate of 10 liters per minute. If it takes 6 minutes to fill up the tank, find the height of the tank?Note that 1 liter = 1000 cm3

Answer 1

The height is 20 cm.

Explanation:

The volume of the tank = 60*50*x cm^3 where x is it's height.

The volume of the water added = the volume of the tank so:

60*50x = 6 * 1,000 * 10

3000x = 60,000

x = 60000/3000

x = 20 cm.
