Question

Find the surface area of a cube whose volume is $216c{m}^3$.

• A. $216c{m}^3$
• B. $362c{m}^2$
• C. $216c{m}^2$
• D. $362c{m}^3$

Answer 1

The correct option is C $216c{m}^2$

$\text{Given, volume,}V=216c{m}^3\text{We know, volume of a cube of side 'a' is}{a}^3.⟹a^3=216⟹a=6cm\text{Now, surface area}=6a^2=216c{m}^2$
