17 expressed as two cubes. Can the sides have irrational or negative length. If no to both, it's impossible.

That's an ... interesting ... opinion since there are several rational solutions given in the previous posts, for instance: 104940/40831 and 11663/40831.

The sides shouldn't be irrational, or negative, but it is possible.
The sides can be rational (not just integer).
