Question

Water is pouring into a cuboidical reservoir at the rate of 6litres per minute. If the volume of the reservoir is 108 metre square. Find the number of hours it will take the reservoir to fill What are the advantages of reservoir for farmers?

Answer 1

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.

Answer 2

108m3=108000l
min=108000÷6
min=16000
60min=1hr
hrs=16000÷60
hrs=244×4/6
