Find the height $ h $ of a triangular prism if side $a = 9$ and length $l = 12$.
Answer
$h = \frac{ 9 \sqrt{ 3}}{ 2 }$
Explanation
To find height $ h $ use formula:
$$ h = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ a = 9 $ we have:
$$ h = \dfrac{ \sqrt{ 3 } \cdot 9 }{ 2 } $$$$ h = \dfrac{ 9 \sqrt{ 3 } }{ 2 } $$ $$ h = \frac{ 9 \sqrt{ 3}}{ 2 } $$This page was created using
