Question
Find the side $ a $ of a cube if face area $FA = 1\, \text{mm}^2$.
Answer
$1\, \text{mm}$
Explanation
To find side $ a $ use formula:
After substituting $FA = 1\, \text{mm}^2$ we have:
$$ FA = a^2 $$ $$ a^2 = 1\, \text{mm}^2 $$ $$ a = \sqrt{ 1\, \text{mm}^2 } $$ $$ a = 1\, \text{mm} $$This page was created using
