Answer:
Asked: Amount of sq. in of paper needed to wrap the box/surface area of the box
Given: l = 20 in, w = 12 in, h = 6 in
Formula: Formula for surface area of rectangular prism: 2(lw + lh + wh)
Solution:
S.A. = 2(lw + lh + wh)
S.A. = 2[(20 in * 12 in) + (20 in * 6 in) + (12 in * 6 in)]
S.A. = 2[(240 sq. in) + (120 sq. in) + (72 sq. in)]
S.A. = 2(432 sq. in)
S.A. = 864 sq. in
Final Answer: She needs 864 sq. in of paper to wrap the entire box.
