Answer:
Marcella will need 717.8 square inches of paper to covert the box with none left over.
Explanation:
- Since we have different dimensions for the box, we know it's a rectangular box (aka a rectangular prism).
- Because Marcella has to cover the box, we want to find the surface area of the box.
The formula for the surface area of a rectangular box is given by:
SA = 2lh + 2lw 2wh, where
- SA is the surface area in units squared,
- l is the length,
- h is the height,
- and w is the width.
If we let 11.75 represent the length, let 12.2 represent the height, and let 9 represent the width, we can now find the surface area of the box by substituting these values for the variables in the rectangular box surface formula:
SA = 2(11.75 * 12.2) + 2(11.75 * 9) + 2(9 * 12.2)
SA = 2(143.35) + 2(105.75) + 2(109.8)
SA = 286.7 + 211.5 + 219.6
SA = 717.8
Thus, Marcella will need 717.8 square inches of paper to covert the box with none left over.
