1. 4 * 8 = 32
2. 4 * 2 = 8
3. 8 * 2 = 16
4. 32 + 8 + 16 = 56
5. 56 * 2 (56 + 56) = 112
So, in conclusion, the answer to this question about the surface area of a rectangular prism with side lengths of 4, 8, and 2 is 112cm squared so, you should strongly go with option D, 112 cm squared. :) Glad I could help!
