It's timed someone plzzz. What is the surface area of the triangular prism?

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 height of 6 feet.

[Not drawn to scale]

115 square feet
120 square feet
135 square feet
150 square feet

the answer should be 131

Step-by-step explanation:

the base of the triangular prism is 2.5x8=20

the 2 sides are equal and is 8x6=48 but there is 2 so it doubles so it is 96

and the 2 triangles are A=1/2 BH but since there is 2 triangles dont divide it should be 2.5x6 and the total should be 131 when added all together

yor answer is 7/6 times 5

step-by-step explanation:

answer: .64
