Answer 1

To find the surface area of the triangular prism, we need to calculate the sum of the areas of all the individual faces.

The net of the triangular prism includes:
- 2 triangular faces with base 9 cm and height 6 cm each: 2 * (1/2 * 9 cm * 6 cm) = 54 cm2
- 3 rectangular faces with dimensions 9 cm x 6 cm, 9 cm x 6 cm, and 6 cm x 6 cm: 3 * (9 cm * 6 cm) + 2 * (6 cm * 6 cm) = 54 cm2 + 36 cm2 = 90 cm2

Total surface area = 54 cm2 + 90 cm2 = 144 cm2

So, the surface area of the triangular prism is 144 cm2.
