Answer:
SA = 280 in²
Step-by-step explanation:
The net comprises:
- 2 rectangles with width 5 in and length 10 in
- 2 rectangles with width 6 in and length 10 in
- 2 rectangle with width 5 in and length 6 in
To calculate the surface area (SA), calculate the area of each rectangle and add them together.
Area of a rectangle = width x length
Therefore, SA of net = 2(5 x 10) + 2(6 x 10) + 2(5 x 6)
⇒ SA = 100 + 120 + 60
⇒ SA = 280 in²
