The side length, s, of a cube is 3x + 2y. if v = s3, what is the volume of the cube?

Explanation:

We have given with a cube whose side is and we need to find  the volume of a cube

Whose volume is defined by

So, according to the formula we will get

Using the fomula

Here a=3x and b=2y substituting in the formula we will get

After simplification we will get

Hence, volume of cube is  

to complete this square you have to rotate about the origin 270 degrees clockwise.
