To find the total surface area of a triangular prism, you'll need to know the dimensions of the triangular base (the lengths of its sides and height) as well as the height of the prism itself.
The formula for the total surface area (SA) of a triangular prism is:
\[ SA = bh + PH \]
where:
- \( b \) is the area of the triangular base,
- \( P \) is the perimeter of the triangular base,
- \( H \) is the height (length) of the prism.
1. Calculate the area \( A \) of the triangular base.
2. Find the perimeter \( P \) of the triangular base by adding the lengths of all three sides.
3. Multiply the height of the prism \( H \) by \( P \) to calculate the lateral area.
4. Finally, add the area of the two triangular bases to the lateral area for the total surface area.
Since you haven't provided specific dimensions, I can't calculate the surface area directly. However, if you have the base's dimensions, please provide them, and I can help you further. Alternatively, if you simply want to select an answer from the provided options, I'd need more context or calculations related to the prism's dimensions to determine which option is correct.
