water is pouring into a cuboidal reservoir at the rate of 60 litres per minute. if the volume of the tank is 108m cube, find the number of hours it will take to fill the reservoir?
Rate of flow of water = 60 litres/minute
Volume of the tank = 108 m3
1 m3 = 1000 litres
108 m3= 108000 litres
Time taken to fill the complete tank = 108000/60 = 1800 minutes = 1800/60 hours = 30 hours
The tank will be filled completely in 30 hours.
