Question

500 men took a dip in a tank which is 80 m long and 50m broad. If a man displaces 4 m^3 water, what is the rise in level of water?

Answer 1

Level of water in the tank = h
Now.,
The amount of water rises in the tank = displacement of water taken by 500persons.

80*50*h = 500*4
4000h = 2000
H = 2000/4000 m
1/2m = 100/2cm = 50cm

50*10mm = 500mm
Thus,the rise of level of water in the tank is 500mm.......

Answer 2

Answer:

Step-by-step explanation:

Volume of water displaced by 500 men =500*4 =2000m cube

Area of tank=80*50=4000 m sq

Let the rise in the level of water=h metres

Then

4000*h=2000

h=2000/4000

h=1/2m

So in cm

h=50 cm
