Calculate Cube Volume: Finding Volume When Side Length is 2X

To find the volume of a cube, we use the formula:

$V = \text{side}^3$

Here, the side length of the cube is given as $2X$. Substituting this into the formula gives:

$V = (2X)^3$

To expand this expression, apply the cube to every part of the expression:

$V = 2^3 \times X^3$

$V = 8 \times X^3$

Thus, the volume of the cube is:

$V = 8X^3$

Therefore, the correct answer is:

$8X^3$

Thus, the solution to the problem is $8x^3$.
