Perfect cube? Tell me more.. I'm interested, and confused :confused:

yeah, you need to define a bit better what you are talking about. what is a "perfect cube" and what do you want to solve about it? do you want the surface of a cube? volume? the cube root of a number? the coordinates of the corners of a cube?

Hey hollywood!

if (Math.pow(cubedNum,1/3)==integer) cubedNum = perfectCube; :D


If a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube. To get the cube root, we simply divide the exponent by 3. For example x^9 is a perfect cube, its cube root is x^3 . x^11 is not a perfect cube.

The following is a list of perfect cubes:

1 = 1
2 = 8
3 = 27
4 = 64
5 = 125
6 = 216
7 = 343
8 = 512
9 = 729
10 = 1000

do you call it algebra?

Sorry I was not clear enough. I never figured it out, but no worries and I passed my final so I am okay.

I ment how do you factor a cubic polymonial: x^3 + x^2 + x + 1

there was some forumla to do it, but I cannot rember. Thanks for the help anyways.
