Find the side $ a $ of a triangular prism if length $l = 10$ and height $h = 11$.
Answer
$a = \frac{ 22 \sqrt{ 3}}{ 3 }$
Explanation
To find side $ a $ use formula:
$$ h = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $ h = 11 $ we have:
$$ 11 = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$ $$ \sqrt{ 3 } \cdot a = 11 \cdot 2 $$ $$ \sqrt{ 3 } \cdot a = 22 $$ $$ a = \dfrac{ 22 }{ \sqrt{ 3 } } $$ $$ a = \frac{ 22 \sqrt{ 3}}{ 3 } $$This page was created using
