Answer 1

The formula for the surface area of a rectangular prism is:
Surface area = (Area of side "x * y" x 2) + (Area of side "x * z" x 2) + (Area of side "y * z" x 2)

$SA = [(l*w) * 2]+[(l*h)*2]+[(w*h)*2]\\SA=[(8\ in*6\ in)*2]+[(8\ in*6\ in)*2]+[(6\ in*6\ in)*2]\\SA=(48\ in^{2}*2)+(48\ in^{2}*2)+(36\ in^{2}*2)\\SA=96\ in^{2}+96\ in^{2}+72\ in^{2}\\\\SA=264\ in^{2]$

Thus, the surface area of the box's gift-wrap is 264 in².
