Given that the water is pouring into a cuboidal reservoir at the rate of 60 litres per minute.

Volume of reservoir is 108\ m^3, then

The number of hours it will take to fill the reservoir will be:

As we know 1m^3 = 1000L.

Then 108\ m^3 = 108,000 Litres ;

Time taken to fill the tank will be:

\frac{1,08,000litres}{60litres\ per\ minute} = 1,800 minutes

or   \frac{1,800hours}{60} =30hours.
