The side length, s, of a cube is x – 2y. if v = s3, what is the volume of the cube?

The volume of cube =  x³ -6x²y + 12xy² - 8y³

Step-by-step explanation:

It is given that,

Side length of cube s = (x - 2y)

Volume of cube = s³

Points to remember

(a - b)³ = a³ - 3a²b + 3ab² - b³

To find the volume of cube

s = (x - 2y)

Volume V = s³ = (x - 2y)³

(x - 2y)³ = x³ - (3 * x² * 2y) + (3 * x * (2y)²) - (2y)³

  = x³ -6x²y + 12xy² - 8y³

Therefore the volume of cube =  x³ -6x²y + 12xy² - 8y³

Step-by-step explanation:

We are given that the side length (s) of a cube is . Given that , we are to find the volume of the cube.

We know that,

So expanding the given expression accordingly:

Volume of cube =
