Like your train of thought !

It's not as simple as that, as the conductor is made up of multiple round strands, and in order for the cable to bend, they need to not be too tightly packed together. It's also affected by the size and how many individual strands there are, that's why you buy cable by area, not the conductor diameter and why the conductor size is bigger than the logical size using that calculation.

Yes the interstitial spaces didn't think about them !
