00:00:00,630 --> 00:00:08,830
Let's do this question, a cowboy little tin box open at the top has dimensions 20 into 16 into 14.

2
00:00:09,210 --> 00:00:14,280
What is the total area of metal sheet required to make 10 such boxes?

3
00:00:14,610 --> 00:00:15,050
All right.

4
00:00:15,330 --> 00:00:16,060
What's the video?

5
00:00:16,080 --> 00:00:18,440
Give it a try and then let's do it together.

6
00:00:20,040 --> 00:00:20,880
All right, we are back.

7
00:00:20,910 --> 00:00:22,140
I hope you have given it a try.

8
00:00:22,380 --> 00:00:24,000
Let's do it together first.

9
00:00:24,000 --> 00:00:27,750
Let's find out the area required for making one such box.

10
00:00:27,960 --> 00:00:28,320
Right.

11
00:00:28,500 --> 00:00:31,560
The area required would be the surface area.

12
00:00:31,560 --> 00:00:31,950
Right.

13
00:00:32,070 --> 00:00:35,600
Because then you just need to fold it in the shape of the box.

14
00:00:35,790 --> 00:00:42,600
So that would be 20 to 16 plus to 20 in the 14 plus two in the 16 into 14.

15
00:00:42,600 --> 00:00:42,900
Right.

16
00:00:43,080 --> 00:00:45,690
Why don't we do 10 to 20 to 16?

17
00:00:45,870 --> 00:00:48,270
Because it's mentioned that the top is open.

18
00:00:48,450 --> 00:00:48,790
Right.

19
00:00:49,020 --> 00:00:54,560
Therefore, you will find that this is equal to one three to eight centimeters square.

20
00:00:54,870 --> 00:00:57,990
Now, that's the area required for one box now.

21
00:00:58,020 --> 00:01:02,660
Hence the area required for 10 boxes will be one three to eight in 10.

22
00:01:02,670 --> 00:01:06,000
That's equal to one three two eight zero centimeter square.
