Question : If the volume of a cube is 1728 cm³, then what is the total surface area of the cube?

Option 2: 729 cm²

Option 3: 864 cm²

Option 4: 926 cm²

Team Careers360 · Accepted Answer

Correct Answer: 864 cm²

Solution : The volume of a cube is given by the formula $V = a^3$, where $a$ is the length of a side.
Given that the volume $V$ is 1728$ ext{ cm}^3$,
$a = \sqrt[3]{V} = \sqrt[3]{1728} = 12 ext{ cm}$
So, the total surface area $A$ of a cube,
$A = 6a^2$
Substituting $a = 12$$ ext{ cm}^2$,
$⇒A = 6 imes (12)^2 = 6 imes 144 = 864 ext{ cm}^2$
Hence, the correct answer is 864 cm².
