Question

In a swimming pool measuring 90m X 40m, 150 men take a dip. If the average displacement of water by a man is 8 m³ , then rise in water level is

Answer 1

Answer:

Step-by-step explanation:

Let h m be the rise in the water level of the swimming pool when 150 men take a dip.  

Then, volume of water displaced = Displacement of water by 150 men

⇒90 m ×40 m ×h m =150×8

⇒h=  

90×40

150×8
