4 inches is deep enough on properly prepared sub surface. I won't do the math, no offense, but others here will I'm sure.
At 231 sq. ft. at 4 inches deep your local concrete delivery company would bring you what you need. DON'T bother with bags, but you might consider renting a mixer if you choose this to be a DIY.

You can get 600mm x600mm concrete slabs for as little as £2.50 each or as much as £12each so it all depends on what slabs you were thinking of in the first place , but saying that natural stone is normally dearer. Have you thought about using Indian slate, If you shop around for it you can get it for about £20 a square mt and it looks great. Hope this helps!

looks like you've got the math answered correctly. Why are people recommending rebar and mesh for dog kennel. Unless you plan on driving over it with a vehicle it is pointless.
Form your slab with 2x4 lumber. It will be 3.5 inches thick this way. Order three yards of mud and go 'til your back is broke.

probably 4 inches thick, throw some rebar all around the perimeter and middle, then lay some mesh wire on top so the mesh wire will be close to the middle of the concrete slab. probably 3 yards would do it. alwayz good to have extra!

since no weight will be on it, you could do 2" thick. That size of a slab should have a 'creases' for weather change expansion. I would suggest one for the width and 2 on the length. One continuous slab will crack without expansion joints. If plan to make it thicker, instead of rebar, use chicken wire. Pull wire up into middle of cement with rake.

4" thick would be good with rebar thats 16" grid. Amount of concrete needed 3 yards that would give you a little extra

Figure the square footage and divide by 27 for the amount of concrete needed.

I would go with 50mm concrete since there is no real weight being taken.
so 10m x 20m x 0.050m = 10 m3 of concrete.

231 square feet x 0.33 feet deep = 76.23 cubic feet
76.23 cubic feet / 27 = 2.82 cubic yards.
add a little extra for waste
