Question

Water is pouring into a cuboidal reservoir at the rate of 60 litres per minute. If the volume of reservoir is 108m3, find the number of hours it will take to fill the reservoir.

Answer 1

Volume of cuboidal reservoir = 108 m3 = ($108 × 1000$) L = 108000 L
It is given that water is being poured at the rate of 60 L per minute.
That is, ($60 × 60$) L = 3600 L per hour
Required number of hours = $\frac{108000}{3600} = 30$ hours
Thus, it will take 30 hours to fill the reservoir.
