You would need 5.26 cubic yards of concrete based on the concrete calculator found at the related link below.
5.5 deep is hard to guarantee in every spot of the slab, so order extra. You would really want between 5.5 and 6 cubic yards. You don't ever want to be short.
If this is an exterior slab that would be exposed to freezing conditions, make sure to order air entrainment and 4,000 psi concrete and don't add an more than 1 gallon of water per cubic yard of concrete. If you want it to be more loose, then ask for a low range water reducer in the mix.
