Find the area $ A $ of a triangular prism if side $a = 14$ and length $l = 26$.
Answer
$A = 1261.741$
Explanation
To find area $ A $ use formula:
$$ A = \frac{ a^2 \sqrt{3}}{2} + 3 a l $$After substituting $ a = 14 $ and $ l = 26 $ we have:
$$ A = \frac{ 14^2 \sqrt{3}}{2} + 3 \cdot 14 \cdot 26 $$$$ A = \frac{ 196 \sqrt{3}}{2} + 3 \cdot 364 $$$$ A = \frac{ 196 \sqrt{ 3 }}{2} + 1092 $$$$ A = 98 \sqrt{ 3 } + 1092 $$$$ A = 1261.741 $$This page was created using
