Step-by-step explanation:

Answer 2

The surface area of the triangular prism is 135 feet squared

How to find the surface area of a triangular prism?

surface area of a triangular prism = (perimeter × length) + (2 × base area)

Therefore,

Surface area of a triangular prism = (6 + 2.5 + 6.5)8 + (2.5 × 6)

Surface area of a triangular prism = (15)8 + 15

Surface area of a triangular prism = 120 + 15

Surface area of a triangular prism = 135 ft²

Therefore, the surface area of the triangular prism is 135 feet squared.
