Let's do this question, 160 metre cube of water is to be used to irrigate a rectangular field whose
area is 800 metres square.
What will be the height of the water level in the field?
All right.
Pause the video and give it a try and then let's do it together.
All right.
We're back.
Let's do it together.
Now, the volume of water that's used for irrigation is given us 160 meter cube.
Right.
But this is poured into a field and it's given that the area of the field.
Is 800 meter square.
Now, remember, we have seen that volume is equal to area of the base into height, right?
Therefore, this 160 has to be equal to the area into height.
And this would be the height to which the water would rise to 160 is equal to 800 in the edge and on
solving.
You get it is equal to one 160, divided by eight hundred, that's equal to zero point two meters and
that's the answer to this question.
