Question

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

Answer 1

Step-by-step explanation:

Given  

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

Displacement of water by 1 man = 3.6 m^3

Total volume of water displaced by 100 men = (3.6 x 100) m^3 = 360 m^3

Rise in water level in a pond is same as the height of volume of cuboid.

Volume = Length x Breadth x height

So rise in water level = 360 / (50 x 18)

                                   = 360 / 900

                                  = 0.4 m

                                  = 40 cm

The rise in the water level​ is 40 cm
