Find the area $ A $ of a triangular prism if side $a = 23$ and length $l = 120.5$.
Answer
$A = 8772.6274$
Explanation
To find area $ A $ use formula:
$$ A = \frac{ a^2 \sqrt{3}}{2} + 3 a l $$After substituting $ a = 23 $ and $ l = 120.5 $ we have:
$$ A = \frac{ 23^2 \sqrt{3}}{2} + 3 \cdot 23 \cdot 120.5 $$$$ A = \frac{ 529 \sqrt{3}}{2} + 3 \cdot 2771.5 $$$$ A = \frac{ 529 \sqrt{ 3 }}{2} + 8314.5 $$$$ A = \frac{ 529 \sqrt{ 3}}{ 2 } + 8314.5 $$$$ A = 8772.6274 $$This page was created using
