Question

A river 15 m deep 50m wide is flowing at the rate of 2 cm per second how many liters of water will fall from the river into the sea in 9 hours?

Answer 1

Her l= 15m
b=50m
h=2cm = 0. 02m
Thus volume of cuboid = l b h
=
$15 \times 50 \times 0.02$
=
15 cubic meters

Now now the litres of water in 1 second is equal to 15 cubic metre thus Area of liter in 9 hours =3600
$\times$
9
=32400sec
$\times$
15= 486000

Answer 2

Answer:

15 cubic metre is the correct answer
