Find the area $ A $ of a triangular prism if side $a = 6$ and length $l = 4$.
Answer
$A = 103.1769$
Explanation
To find area $ A $ use formula:
$$ A = \frac{ a^2 \sqrt{3}}{2} + 3 a l $$After substituting $ a = 6 $ and $ l = 4 $ we have:
$$ A = \frac{ 6^2 \sqrt{3}}{2} + 3 \cdot 6 \cdot 4 $$$$ A = \frac{ 36 \sqrt{3}}{2} + 3 \cdot 24 $$$$ A = \frac{ 36 \sqrt{ 3 }}{2} + 72 $$$$ A = 18 \sqrt{ 3 } + 72 $$$$ A = 103.1769 $$This page was created using
