Example, assuming the cubed numbers based on natural numbers,
6^3=216;
7^3=343.

The cube numbers are 216 and 343.

Another example, How many numbers between 9 and 6? There are 7 and 8, and these are TWO numbers, both between 9 and 6. , which is one too many; so , the quantity of numbers (whole) between 9 and 6.

Return to first example, 343-216-1=126 whole numbers between 7^3 and 6^3.
Try to symbolize this in variables.

Let n be a whole number. Two consecutive cubes based on n would be and . The quantity of whole numbers between these two cubes is , which you may simplify if desired.
