pouring a sauna foundation

This is a layout of the setup I have for my sauna:

From what I have calculated I will need about 2.2 cubic yards of cement.

That is based on :

8' x 1.5' x 1.5' = 18.00 cubic ft.
8' x 1.5' x 1.5' = 18.00 cubic ft.
9' x 1.5' x 1.5' = 20.25 cubic ft.

The space for this sauna is pretty centrally located on my property and I will probably be carrying in the cement for this and mixing it in a mixer with help from a friend.

This foundation will be supporting a cinderblock retaining wall that will be about 8' - 10' feet in the back and taper down as needed on the two sides.

Can I use Quickcrete for this application?

Am I better off buying bags of Portland cement / sand / aggregate and making my own mix?

How do I accurately calculate the amount of Quickcrete and or Cement/Sand/Aggregate mix I will need? (If I have done it wrong)

Any other suggestions or things I need to take into account would be appreciated! Thanks!

Go to the how to section----there is a calculator there for bags of concrete---

I'm not a mason or engineer --so that's all I've got.

I don't see the "cinderblock" retaining wall you mentioned. If it is really retaining 8-10 feet of soil, it needs to be carefully engineered, and certainly cannot be made from cinderblock, but most likely would have to be either segmental block retaining wall with reinforcing or cast in place reinforced concrete. Or perhaps I don't understand what you are saying at all.
