50 men took a dip in a water tank 40 m long and 20 m broad on a religious day. If the average displacement of water by a man is 4 m3, then the rise in the water level in the tank will be:
Answer: Option
Explanation:
Total volume of water displaced = (4 x 50) m3 = 200 m3.
 Rise in water level = |
 |
200 |  m 0.25 m = 25 cm. |

Why should we consider the shape as cuboid?

Guys could anyone explain me.
How they find rise in water level = volume/(l*b)?
Whether any formula is there to find out rise of water level?
How they find rise in water level = volume/(l*b)?
Whether any formula is there to find out rise of water level?

Displacement of water by 1 man = 4 m3.
Total volume of water displaced by 50 men = (4 x 50) m3 = 200 m3.
Rise in water level in the tank is same as the height of the volume of cuboid.
Volume = Length x Breadth x Height.
Rise in water level = 200/(40 x 20) = 0.25 m or 25 cm.
Total volume of water displaced by 50 men = (4 x 50) m3 = 200 m3.
Rise in water level in the tank is same as the height of the volume of cuboid.
Volume = Length x Breadth x Height.
Rise in water level = 200/(40 x 20) = 0.25 m or 25 cm.

How can a man displace 4000 liters?

Water displaced is only equal to the rise in water level but not to the total volume of tank.
