Answer:

2,124 in.²

Step-by-step explanation:

The box has the following dimensions:

L = 24 in.

W = 18 in.

H = 15 in.

The square inches of paper used by Sam = surface area of the box(rectangular prism)

Surface area = 2(LW + LH + WH)

Surface area = 2(24×18 + 24×15 + 18×15)

Surface area = 2(432 + 360 + 270)

Surface area = 2(1,062)

Surface area = 2,124 in.²
