## official_snowflake 3 years ago What is the lateral area of a triangular prism with base edges all equaling 4 feet and a height of 10 feet?

1. official_snowflake

I'm so torn.. is it 160 or 120? Both explanations for the answers make sense to me... D;

2. AravindG

LSA=Base perimeter $$\times height$$

3. AravindG

4. official_snowflake

16 x 10... which is 160. Is that really it? I might just be over thinking things.. xD
