Answer:
She needs 40 ft² of wrapping paper to cover the box without overlapping.
Step-by-step explanation:
Consider the provided information.
She has a box that measures 4 ft. x 2 ft. x 2 ft.
We need to find how many square feet of wrapping paper does she need to cover the box without overlapping.
We can find the square feet of wrapping paper by using the formula of surface area:
SA=2lw+2lh+2hw
Use the above formula and substitute l=4, w=2 and h=2
SA=2(4)(2)+2(4)(2)+2(2)(2)
SA=2(8)+2(8)+2(4)
SA=16+16+8
SA=40 ft²
Hence, she needs 40 ft² of wrapping paper to cover the box without overlapping.
