Question

If volume of cube is $100$ cubic units. Find its length.

• A. $\sqrt[3]{3100}$
• B. $10\sqrt{2}$
• C. $10$
• D. $\sqrt{100}$

Answer 1

Answer: (A)

$\sqrt[3]{3100}$

Given, volume of cube $V=100$ cubic units.

We need to find its length, i.e. side of the cube.

We know, Volume of a cube $V=a^3$, where $a$ is the side of the cube.

Therefore, $100=a^3$
$\therefore a=\sqrt[3]{3100}$ unit.

Hence, option $A$ is correct.
