Answer 1

Answer:

135 square feet.

Step-by-step explanation:

A triangular prism. The rectangular sides are 8 feet by 2.5 feet, 8 feet by 6 feet, and 8 feet by 6.5 feet. The triangular sides have a base of 2.5 feet and a height of 6 feet.

The prism has two triangular faces and three rectangular faces.

So, the surface area of the prism will be

$2(\frac{1}{2} \times 2.5 \times 6) + (8 \times 2.5) + (8 \times 6) + (8 \times 6.5)$

= 15 + 20 + 48 + 52

= 135 square feet. (Answer)
