Which expression is a sum of cubes?

A cube is an integer that you can get by multiplying a number by itself 3 times.
e.g.: 1 * 1 * 1 = 1; therefore 1 is a cube.
e.g.: 3 * 3 * 3 = 27; therefore 27 is a cube.

Two cubes added together can be factorized into a simpler form.

i.e.:

x {3} + y {3} = 0
can be simplified into:

(x + y)(x^(2) - xy + y^(2) )
