Question
Find the height $ h $ of a triangular prism if side $a = 7.5\, \text{cm}$ and length $l = 20\, \text{cm}$.
Answer
$6.4952\, \text{cm}$
Explanation
To find height $ h $ use formula:
$$ h = \dfrac{ \sqrt{ 3 } \cdot a }{ 2 } $$After substituting $a = 7.5\, \text{cm}$ we have:
$$ h = \dfrac{ \sqrt{ 3 } \cdot 7.5\, \text{cm} }{ 2 } $$$$ h = \dfrac{ 12.9904\, \text{cm} }{ 2 } $$ $$ h \approx 6.4952\, \text{cm} $$This page was created using
