Length X Width X Height / 27 = cubic yards.
30ft x 26ft x 0.33ft (4" being 1/3rd of a foot) = 257.4 cubic feet
257.4/27 = 9.53333 cubic yards of concrete. Order 10 yards and run your entrance forms out front and use the extra for a entrance pad if you have more than enough.

Most trucks carry 10 yards, and I've often seen them come up "short", at least by my calculations. If you are off a bit on your measurements, you may need more concrete. Tell them in advance that you may need another yard, but that you have measured carefully.
If your slab is really 3.5" thick, that's 8.4 yards, so you would have a little extra. If it's 4" and you have low spots (more than 4") you could come up short with 10 (4 1/4" deep would take 10 1/4 yards). Just make sure that 11th yard will be available so you don't have to have a cold joint.
