Answer:
416 mi
Step-by-step explanation:
In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.
Remember to find the area it is length x width
- 9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
- Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
- In total, you will add 72+72+72+72+64+64 which equals 416
