6 and 8, but:

Hexa as in Hexa-Decimal mean 16 number system. ie: 0123456789ABCDEF : 16 digits. 10 decimal + 6 hexa.

Octa as in a numbersystem mean 8 number system. ie: 01234567 : 8 digits.

A Hexagon is a polygon with 6 sides.

An Octagon has got 8 sides.

Examples of numbers in these number systems:

10, 12, 14 =Decimal

A, C, E = HexaDecimal

12, 14, 16 = OctaDecimal

All representing the same number just in different systems.

Additional information:

We use the Decimal number system because it is by far the easiest to do calculations with. It has become a world wide standard.

We use HexaDecimal and Binary in computers.

Octa as in a number system has got no widespread uses as to my knowledge. It might be used in various coding schemes to make information less obviously visible.
