Improved Answer:-
They mean 6 and 8 respectively
5 = penta 6 = hexa 7 = hepta 8 = octa 9 = nona 10 = deca
i think it means deca-octa hydrate..
Both of does prefixes mean not. In this case, these prefixes make words the opposite of what they mean.

The classical Latin and Greek languages are the sources of the prefixes 'octa-', 'hexa-', and 'penta-'. The prefixes respectively mean 'eight', 'six', and 'five'. They come into English by way of the Latin of the ancient Romans and by way of the even earlier Greek of the ancient Greeks.

The prefixes in chemistry are used to indicate the quantity of atoms in a chemical compound. Common prefixes include mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, and deca-. These prefixes are placed before the element name to specify the number of atoms present.
Octa- the prefix means eight. Penta- the prefix means five.

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.
No, "penta" does not mean six; it means five. The prefix for six is "hexa." These prefixes are derived from Greek, where "penta" signifies five (like in pentagon), and "hexa" signifies six (as in hexagon).
Have someone help you edit your question; we can't quite understand what you want to know. There are many different kinds of polygon, polygon is a general term for any enclosed plane figure with straight sides. If you take away the 'poly' and add other prefixes like penta-, hexa- octa- or deca-, that tells you how many sides that polygon has. Penta means 5, hexa means six, octa means 8, deca means 10. There are many other ways to describe polygons.

Yes, hexa does mean 6. It is derived from the Greek word "hex" which means six.
