Agift box in the shape of a rectangular prism measures 8 inches by 8 inches by 10 inches what is the least amount of wrapping paper needed to wrap the gift box answer

The first thing we must do for this case is to find the surface area of the rectangular prism.
 We have then:
 A = 2 * (l * h) + 2 * (h * w) + 2 * (w * l)
 Where,
 w: width
 l: long
 h: height
 Substituting values we have:
 A = 2 * (10 * 8) + 2 * (8 * 8) + 2 * (8 * 10)
 A = 448 in ^ 2
 
 the least amount of wrapping paper needed to wrap the gift box answer is:
 A = 448 in ^ 2
