Take π =3. 14
Answer:
384, 216, 290, 192, 384
1446, 1 roll
Step-by-step explanation:
For rectangular boxes, calculate the sum of each side, then multiply it by two.
Box 1: 2(18 x 5) + 2(18 x 4) + 2(5 x 4) = 364
Box 3: 2(11 x 8) + 2(8 x 3) + 2(3 x 11) = 290
Box 5 is a cube (all sides equal), so you can find 1 side's area and multiply it by 6.
Box 5: 6(8 x 8) = 384
For triangular boxes, calculate the edges, then find the triangular area using area = 0.5(base x height).
Box 2: (15 x 3) + (9 x 3) + (12 x 3) + 2(0.5)(9 x 12) = 216
Box 4: 2(13 x 2) + (10 x 2) + 2(0.5)(10 x 12) = 192
Total: 364 + 290 + 384 + 216 + 192 = 1446
Rolls of wrapping paper:
Area of 1 roll = 30 x 60 = 1800
Since 1446 is less than 1800, you only need 1 roll of wrapping paper.

Answer:
The legs are 1.9 feet long
And the base is 1.1 feet long.
Step-by-step explanation:
Firstly, you need to find the value of x.
You need to add all the sides together:
2x - 0.3 + 2x - 0.3 + x
Simplified =
5x - 0.6
And this equals 4.9:
5x - 0.6 = 4.9
Next, you need to move the -0.6 over to the other side, making sure to make it a positive:
5x = 4.9 + 0.6
5x = 5.5
Now divide each side by 5:
x = 1.1
As the image is unclear of what side you are finding the length of:
2x - 0.3 = 1.9 feet long
And the base is 1.1 feet long.
