Question

12. Through a river 8 m wide 10 m deep water is flowing at a rate of 10 km/hr into a sea.
Find the amount of water flown into sea in 10 hours in litres.

​

Answer 1

Answer:

8000000 Litres

Step-by-step explanation:

L = 10 km

time = 60 mins

B = 8 m

H = 10 m

volume = L× B × H

Therefore volume is 10×8×10 =800 m³

So 800 m³ water is flowing per hour

Therefore 10 hours = 800×10 = 8000 m³

1000 Litre = 1 m³

So 8000m³ = 8000000 Litres

Answer 2

Step-by-step explanation:

Area through which water is flowing

=8*10

=80 sq m

now the volume pass through the area is

=80*10000=800000 cubic metre per hour

in 10 hour

=800000*10=8000000 cubic metre

so amount of water in litre

=8000000*1000=8000000000 litre
