Final answer:
The formula for finding the surface area of a triangular prism is SA = lw + lh + wh.
Step-by-step explanation:
The formula for finding the surface area of a triangular prism is given by:
SA = lw + lh + wh
where:
- l is the length of the prism
- w is the width of the prism
- h is the height of the prism
To find the surface area, you need to know the values of l, w, and h and substitute them into the formula. Then, perform the necessary calculations to find the final answer.
Therefore, option b) SA = lw + lh + wh is the correct formula for finding the surface area of a triangular prism.
