Re: can anybody tell me.. how to calculate the cable dimension

For a circle, A = πr2. Hexagonally packed circles occupy ~91% of the infinite plane, but a stranded cable has gaps around the circumference that reduce this to ~80%, with some variation. In this case, A ≈ 0.8 πr2. Then you must consider the insulation thickness. Because of this, rather than calculating it, one usually looks it up in cable manufacturers' catalogs.
