00:00:00,590 --> 00:00:08,390
Let's do this question, 160 metre cube of water is to be used to irrigate a rectangular field whose

2
00:00:08,390 --> 00:00:10,540
area is 800 metres square.

3
00:00:10,730 --> 00:00:13,610
What will be the height of the water level in the field?

4
00:00:13,940 --> 00:00:14,360
All right.

5
00:00:14,360 --> 00:00:17,390
Pause the video and give it a try and then let's do it together.

6
00:00:17,840 --> 00:00:18,230
All right.

7
00:00:18,230 --> 00:00:18,650
We're back.

8
00:00:18,680 --> 00:00:19,630
Let's do it together.

9
00:00:19,850 --> 00:00:25,940
Now, the volume of water that's used for irrigation is given us 160 meter cube.

10
00:00:25,940 --> 00:00:26,270
Right.

11
00:00:26,540 --> 00:00:31,760
But this is poured into a field and it's given that the area of the field.

12
00:00:32,790 --> 00:00:35,160
Is 800 meter square.

13
00:00:36,850 --> 00:00:43,270
Now, remember, we have seen that volume is equal to area of the base into height, right?

14
00:00:43,530 --> 00:00:48,430
Therefore, this 160 has to be equal to the area into height.

15
00:00:48,550 --> 00:00:55,390
And this would be the height to which the water would rise to 160 is equal to 800 in the edge and on

16
00:00:55,390 --> 00:00:56,050
solving.

17
00:00:57,140 --> 00:01:04,160
You get it is equal to one 160, divided by eight hundred, that's equal to zero point two meters and

18
00:01:04,160 --> 00:01:05,690
that's the answer to this question.
