Question
Find the side $ a $ of a triangular prism if length $l = 38.6\, \text{cm}$ and height $h = 12.4\, \text{cm}$.
Answer
$14.3183\, \text{cm}$
Explanation
To find side $ a $ use formula:
$$ h = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $h = 12.4\, \text{cm}$ we have:
$$ 12.4\, \text{cm} = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$ $$ \sqrt{ 3 } \cdot a = 12.4\, \text{cm} \cdot 2 $$ $$ \sqrt{ 3 } \cdot a = 24.8\, \text{cm} $$ $$ a = \dfrac{ 24.8\, \text{cm} }{ \sqrt{ 3 } } $$ $$ a \approx 14.3183\, \text{cm} $$This page was created using
