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

it is a reproduction.

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
