Answer:
She would pay $36.36 to cover the whole box.
Step-by-step explanation:
You need to find the area of all sides of the box and add them together first.
So, 8x6 = 48
48x2 = 96 (Two of the same sides)
6x11 = 66
66x2 = 132 (Two of the same sides)
8x11 = 88
88x2 = 176 (Two of the same sides)
Add all of those together to get 404 sq inches.
Multiply 404 x 0.09 (the 9 cents) to get your answer of $36.36! Hope this helped!
