Question

100 men took a dip in a pond 50 m long and 18 m wide. if the average displacement of water by a man was 3.6, then calculate the rise water level.

Answer 1

Answer:

the rise in the water level is 0.4 meters.

Step-by-step explanation:

When every man gets into the pond, he displaces 3.6 cubic meters of water.

Now, 100 men took a dip into the tank.

The total volume of water displaced is therefore:

Total volume = 100 × 3.6 = 360 cubic meters

The dip is in form of a cuboid.

The volume of a cuboid = Length × width × height

Substituting the values we have:

360 m³ = 50 × 18 × h

360 m³ = 900 h

h = 360/900 = 0.4 meters.

The rise in water level is 0.4 meters.
