500 men took dip in a tank which is 80 m long, 50 m broad. What is the rise in water level if the average displacement of water by a man is 4 m³.

Solution

Average Displacement by a man = 4m3

=> Total Displacement of water = 4 * 500 = 2000m3

Total Displacement = L X b X H

=> 2000 = 80 X 50 X H

=> 2000 = 4000 X H

=> H = 2000/4000

=> H= 1/2m

=> The water level rose by 0.5m or 50cm.
