Phantasy [73]
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
