Answer:
D, or 432 Inches Squared
Explanation:
First we have to find each side
Front = 6 x 12, 72
Side = 6 x 8, 48
Bottom/Top = 12 x 8, 96
Next we multiply each side by 2, since there is 2 sides for each respective surface.
72 x 2 = 144
48 x 2 = 96
96 x 2 = 192
Lastly, we add them all together, since we are finding surface area!
144 + 96 + 192 = 432
