    Answer:

    352

    Step-by-step explanation:

    Simply you would just add all the side areas together. Since it is a rectangular prism, there are six sides with parallel sides. You have 8 inches as the width x2, 12 inches in length x2, and 4 inches in height x2. Height is 4, so you would multiply that with the side length of 12 getting 48 and since there are 2, it would be 96. Then again multiply the height with the width of 8 inches to get the area of 32 and since there are two of those it would equal 64. Lastly you have length and the width so multiply 8 and 12 to get 96. There are also two of those so you would have 192. In total, you have 96, 64, and 192 so together this would be 352. Your surface area is 352.
