Question

LeAnn wants to giftwrap a present she got for her little brother. How many square inches of giftwrap will be needed to cover a box that is 4in x 6in x 2in? In your final answer, include all of your calculations.

Answer 1

For this case we must find the surface area of a rectangular prism.
 We have then:
 $A = 2 * (w * l) + 2 * (w * h) + 2 * (l * h)$
 Where,
 w: width
 l: long
 h: height
 Substituting values we have:
 $A = 2 * (4 * 6) + 2 * (4 * 2) + 2 * (6 * 2) A = 88 in ^ 2$
 Answer:
 There will be needed 88 in ^ 2 of giftwrap to cover the box
