Answer:
376 inches^2
Explanation:
1. Divide up each type of rectangle
- 10x6
- 6x8
- 8x10
2. Find the area of each rectangle
- 10x6=60
- 6x8=48
- 8x10=80
3. Multiply each rectangle by two to get the opposite one
- 60x2=120
- 48x2=96
- 80x2=160
4. Add them together
120+96+160=376
The surface area is 376 inches^2
