Find the body diagonal $ d $ of a cube if side $a = 12\, \text{cm}$.
Answer
$12 \sqrt{ 3 }\, \text{cm}$
Explanation
To find body diagonal $ d $ use formula:
$$ d = \sqrt{ 3 } \cdot a $$After substituting $a = 12\, \text{cm}$ we have:
$$ d = \sqrt{ 3 } \cdot 12\, \text{cm} $$ $$ d = 12 \sqrt{ 3 }\, \text{cm} $$This page was created using
