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. |

How water displacement is equal to the total volume of the tank along with the height as the rise of water?

L*b*h=Total water displaced=200(given)
now we have to find height i.e rise in the water level
h=200/L*B
H=25cm
now we have to find height i.e rise in the water level
h=200/L*B
H=25cm

They simply used the formula l*b*h, here u need too find the height=total water /l*b
