D because the rest can be divided into cubes or rectangles.
Answer:
Each side is 2 inches long.
Step-by-step explanation:
Volume is Length x Width x Height
For a cube, all sides are the same so you need to figure out what number you can cube (multiply by it self 3 times) to get it to 8.
2 x 2 x 2 = 8
So, each side is 2 inches long.
You can solve this problem through factoring.
First, you have the equation,

Then, you can factor the numerator.

You can cancel out the x-6 in both the numerator and the denominator because they would equal to just 1.
You are left with 
The function is removable noncontinuous at x=6 because if you plug in 6 in x-6, your denominator would be undefined.
