Question

If the side of a cube is $x$, then its volume is ___.

• A. $x$
• B. $x^2$
• C. $x^3$
• D. None of the above

Answer 1

The correct option is C $x^3$

Given, the side of a cube is $x$.
In a cube, all sides are of equal length. Hence, length = breadth = height = $x$
Now, volume of the cube is $x\times x\times x=x^3$
