goryon13,
If you do as proposed you will need 4.8 cu metres of mix. You could ignore the cement used to make the mix because bulking of the sand will compensate for the extra volume. The sand/aggregate mix should be about 50/50.
BUT
With the area you are describing 4" of concrete will crack and break especially when laid on dirt. I suggest you increase the depth to 6" and incorporate reinforcing mesh in the concrete.
