Question
Find the lateral area $ LA $ of a triangular prism if side $a = 4\, \text{cm}$ and length $l = 10\, \text{cm}$.
Answer
$120\, \text{cm}^2$
Explanation
To find lateral $ AL $ use formula:
$$ AL = 3 \cdot a \cdot l $$After substituting $a = 4\, \text{cm}$ and $l = 10\, \text{cm}$ we have:
$$ AL = 12\, \text{cm} \cdot 10\, \text{cm} $$$$ AL = 120\, \text{cm}^2 $$This page was created using
