1. Answer:

   S(A) = 306 in²

   Step-by-step explanation:

   The surface area of a rectangular prism can be found using the following equation:

   SA(rectangular prism) = 2(wl + hl + hw)

   Note:

   w = width = 6

   h = height = 12

   l = length = 4.5

   Plug in the corresponding numbers to the corresponding variables:

   SA(rectangular prism) = 2((6 * 4.5) + (12 * 4.5) + (12 * 6))

   SA(rectangular prism) = 2((27) + (54) + (72))

   SA(rectangular prism) = 2(27 + 54 + 72)

   SA(rectangular prism) = 2(153)

   SA(rectangular prism = 306

   S(A) = 306 in²
