Find the base area $ B $ of a triangular prism if side $a = 10$ and height $h = 8$.
Answer
$B = 25 \sqrt{ 3 }$
Explanation
To find base area $ B $ use formula:
$$ B = \dfrac{ \sqrt{ 3 } \cdot a^2 }{ 4 } $$After substituting $ a = 10 $ we have:
$$ B = \dfrac{ \sqrt{ 3 } \cdot 10^2 }{ 4 } $$ $$ B = \dfrac{ \sqrt{ 3 } \cdot 100 }{ 4 }$$ $$ B = \dfrac{ 100 \sqrt{ 3 } }{ 4 }$$ $$ B = 25 \sqrt{ 3 } $$This page was created using
