Find the side $ a $ of a pyramid if slant height $s = 7$ and lateral surface $L = 10$.
Answer
$a = \frac{ 5 }{ 7 }$
Explanation
To find side $ a $ use formula:
$$ L = 2 \cdot a \cdot s $$After substituting $ L = 10 $ and $ s = 7 $ we have:
$$ 10 = 2 \cdot a \cdot 7 $$$$ 10 = 14 \cdot a $$$$ a = \dfrac{ 10}{ 14 } $$$$ a = \frac{ 5 }{ 7 } $$This page was created using
