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
