Question

Pls help bro ima fail

Answer 1

$24

Explanation:

Dimensions: 14 x 8 x 4

It's asking what the cost is if you cover 3 boxes, not the volume, so we have to find the surface area of 1 box then multiply it by 3, then multiply by 0.02

The formula for a rectangular prism is:

2(wl+hl+hw)

2((8x14)+(4x14)+(4x8)

=400

Now, there are 3 boxes, so 400x3 = 1,200

1,200 x 0.02 = 24

So, it will cost $24 to cover 3 shoe boxes, hope this helps :)

Answer 2

$24

Explanation:

im assuming that height is 4 since thats what it looks like...

surface area of 1 box (wrapping for 1 box): 2*[(14*8)+(14*4)+(8*4)] = 400 square inches

Surface area of 3 boxes(wrapping for 3 boxes): 400*3 = 1200 square inches

cost: 1200 * 0.02 = 24
