Question

Water is being poured into a cuboidal tank at the rate of 80 L/min. If the volume of tank is 14.4 m cube then find the no. of hours it will take to fill the tank

Answer 1

As the volume of the cuboidal tank is 14.4 cubic metre, then its volume can also be written as 14.4×1000000=14400000 cubic centimetre. So, now 1 litre = 1000 cubic centimetre, so the capacity of the tank will be of 14400000÷1000=14400 litres. Divide 14400 by 8, which equals 140 mins. or 2 hours 20 mins.
