Question
Find the side $ a $ of a pyramid if slant height $s = 7\, \text{cm}$ and lateral surface $L = 10\, \text{cm}$.
Answer
$0.2274$
Explanation
To find side $ a $ use formula:
$$ L = 2 \cdot a \cdot s $$After substituting $L = 10\, \text{cm}$ and $s = 7\, \text{cm}$ we have:
$$ 10\, \text{cm} = 2 \cdot a \cdot \left( 7\, \text{cm} \right)^{4} $$$$ 10\, \text{cm} = 14\, \text{cm} \cdot a $$$$ a = \dfrac{ 10\, \text{cm}}{ 14\, \text{cm} } $$$$ a \approx 0.2274 $$This page was created using
