Is the number 2 a cubed number?

Answer 1

No.

I think you mean "Is the number 2 a cubic number?" meaning, "Is there any number cubed that will equal 2?".

The first cubic number is 1 (13), then 8 (23). So the cubic numbers skip straight past 2.

But really if you're asking "Is 2 a cubed number?", then yes it can be. A cubed number would just suggest, "can you cube the number 2"? And yes, 2 cubed = 8.
