Question

The total surface area of a cube is 384 $m^2$. Its volume will be :

• A. $343m^3$
• B. $616m^3$
• C. $512m^3$
• D. $660m^3$

Answer 1

The correct option is C $512m^3$

Using formula, Total surface area of cube
$=6\times {\left(side\right)}^2$
$384=6{\times \left(side\right)}^2$
$\Rightarrow Side=8m$
Volume of cube ${\left(Side\right)}^3=512m^3$
