Question
Find the lateral area $ L $ of a pyramid if side $a = 5\, \text{cm}$ and slant height $s = 10\, \text{cm}$.
Answer
$100\, \text{cm}^2$
Explanation
To find lateral surface $ L $ use formula:
$$ L = 2 \cdot a \cdot s $$After substituting $a = 5\, \text{cm}$ and $s = 10\, \text{cm}$ we have:
$$ L = 10\, \text{cm} \cdot 10\, \text{cm} $$$$ L = 100\, \text{cm}^2 $$This page was created using
