Question

Water in a cuboidal reservoir is pouring in at the rate of 20 litres per minute. If the volume of reservoir is 156 m³. Find the number of hours it will take to fill the reservoir.​

Answer 1

Answer:

Step-by-step explanation:

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.

= Rate of flow of water = 60 litres/minute

= Volume of the tank = 108m³

= 1m³=1000 litres

= 108 m³ = 108000 litres

= Time taken to fill the complete tank = 108000/60 = 1800 minutes = 1800/60= 30 hours

= The tank will be filled completely in 30 hours
