Question

1000 persons are taking dip into a cuboidal pond which is 80m long and 50m broad.What is a rise of water level in the pond if average displacement of water by a person is 0.4m3?​

Answer 1

Answer:

Let the rise of water level in the pond be hm, when 1000 persons are taking a dip into a cuboidal pond. Given that,

Step-by-step explanation:

lenght of cuboid =80m

breath=50m

Now,volume for rise of the water level in the pond =L*b*h

80*50*h=4000h

and average displacement of the water by a person =0.04m3

So.

the average displacement of the water by 1000 persons =1000*0.04

Now given condition

Volume of the water raise in the pond

=average displacement of water by

1000 persons

.

. . 4000h=1000*0.04

h=1000*0.04/4000

h=40/4000

h=1/100

=0.010m

=0.010*100cm

= 0.10cm
