Question

What is the surface area of the triangular prism?

Answer 1

Option B.
`724\ cm^(2)`

Explanation:

we know that

The surface area of the triangular prism is equal to

`SA=2B+PL`

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the triangular prism

Find the area B

`B=(8)(15)/2=60\ cm^(2)`

Find the perimeter P

`P=(8+15+17)=40\ cm`

we have

`L=15.1\ cm`

substitute the values

`SA=2(60)+(40)(15.1)=724\ cm^(2)`
