Problema Solution
Kelly is wrapping paper around a box. The box is 18 in. long, 12 in. wide, and 3 in. high. What is the minimum amount of paper Kelly needs to completely wrap the box?
Answer provided by our tutors
we need to find the area of the box that measures 18 in. long, 12 in. wide, and 3 in. high
A >= 2(length*width + width*height + length*height)
A >= 2(18*12 + 12*3 + 18*3)
A >= 612 in^2
Kelly needs minimum 612 in^2 of wrapping paper.
