Question

Water is pouring into a cubiodal reservoir at the rate of $60$ litres per minute. If the volume of reservoir is $108m^3$, find the number of hours it will take to fill the reservoir.

Answer 1

Volume of cubiod $=108m^3=108000l$

Volume of water in $1$ hour is $=60\times 60=3600l$

Number of hours$=\frac{108000}{3600}=30$ hours
