Question

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

Answer 1

Given:

$\Rightarrow$Volume of cuboidal reservoir $=108m^3$

$\Rightarrow$Volume of cuboidal reservoir $=108\times 1000=108000l$ .............. As $1m^3=1000l$

Rate of water flow $=60$ litres/minutes

$\Rightarrow$Required number of hours $=$ $\left(\frac{108000}{60\times 60}\right)=30$ hours

$\Rightarrow$So, it will take $30$ hrs to fill the reservoir
