Question

How do I find the surface area of this triangular prism?

a) SA = 2(lw + lh + wh)
b) SA = lw + lh + wh
c) SA = l² + w² + h²
d) SA = 3(lw + h)

Answer 1

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.
