Water is pouring into a cubiodal reservoir at the rate of 60 litres per minute. If the volume of reservoir is 108 m3, find the number of hours it will take to fill the reservoir.
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 = `108000/3600` = 30 hour
Thus, it will take 30 hours to fill the reservoir.
