Find the area $ A $ of a cube if volume $V = 10.6522\, \text{cm}$.
Answer
$29.0476$
Explanation
STEP 1: find side $ a $
To find side $ a $ use formula:
After substituting $V = 10.6522\, \text{cm}$ we have:
$$ V = a^3 $$ $$ a^3 = 10.6522\, \text{cm} $$ $$ a = \sqrt[3]{ 10.6522\, \text{cm} } $$$$ a \approx 2.2003 $$STEP 2: find area $ A $
To find area $ A $ use formula:
$$ A = 6 \cdot a^2 $$After substituting $a = 2.2003\, \text{cm}^0$ we have:
$$ A = 6 \cdot 2.2003 $$ $$ A = 29.0476 $$ $$ A = 29.0476 $$This page was created using
