Question

Erin covered a box with contact paper. The dimensions of the box are shown in the figure below:

A rectangular prism is shown. The length of the rectangular prism is labeled as 11 inches, the height is labeled as 9 inches and the width is labeled as 8 inches.

The contact paper costs 8¢ per square inch. She will only pay for the contact paper used to cover the box, even if there is waste or extra. How much money did Erin spend on the contact paper?

Answer 2

Answer 3

the options are: $20.72 , $ 41.44, $ 48.12,and $ 73.14

Answer 4

So we are trying to find surface area right?

Answer 5

I think,im re-reading through all the lessons but math is my worst subject

Answer 6

well to get surface area the equation is 2(lw + wh + lh)
so lets input the numbers. 2( 11(8) + 8(9) + 11(9) ) so try figuring out the total

Answer 7

519?or 518 i think

Answer 8

Great Job its 518! So now we know the surface area which is 518 in^2 now we neede to know how much it'll cost to buy the paper. We know that is it 8 cents per square inch so we are going to multiply 8 cents by 518.

Answer 9

Correct! So the total is $41.44 which is one of the answers!
