Question
Find the base area $ B $ of a triangular prism if side $a = 1.6\, \text{cm}$ and length $l = 8\, \text{cm}$.
Answer
$1.1085\, \text{cm}^2$
Explanation
To find base area $ B $ use formula:
$$ B = \dfrac{ \sqrt{ 3 } \cdot a^2 }{ 4 } $$After substituting $a = 1.6\, \text{cm}$ we have:
$$ B = \dfrac{ \sqrt{ 3 } \cdot \left( 1.6\, \text{cm} \right)^{2} }{ 4 } $$ $$ B = \dfrac{ \sqrt{ 3 } \cdot 2.56\, \text{cm}^2 }{ 4 }$$ $$ B = \dfrac{ 4.4341\, \text{cm}^2 }{ 4 }$$ $$ B = 1.1085\, \text{cm}^2 $$This page was created using
