If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
You will need a minimum of 39.51 Cubic Yards.
5 yds - One yard of concrete will cover approximately 81 square feet 4" deep.

A conventional slab will have two bars side by side near the top and bottom of each beam and a 16" grid across the entire top of the slab. Can't help you with a post tention... they are inventing new ways to take steel out of them every day.
Depends on size and thickness. You take length x Width x Thickness= Then Divide by 27. That will give you How many yards of concrete you need. Then you need to call your local concrete company and get a price per yard. Multiply your yards with price and the you have your price Just for your concrete. Now as far as having somebody to the whole process for you i would call around and get as many estimates as possible to compare prices.

12-ft x 12-ft x 2-in = 24 cubic feet = 8/9 of 1 cubic yard
That's going to depend on the shape of the cubic meter, because the drying happens where the concrete is in contact with the air. A slab will dry faster than a cube or a pier.
Take the slab out and pour a new one with the right slope. Rent a concrete saw and cut a few grooves in it making the groove deeper away from the house. This will let the water drain off of the slap and away from the house. If the slab is separate from the house, you might be able to mud jack it at the house and raise it enough to slop it away from the house. Mud jacking is not terribly expensive.
3ftx3ftx3ft you have to know how thick your slab is going to be if your slab is 3in it takes 4-3ft x 3ft to equal 1/3 of a cu yard so 12 3ft x 3ft squares will take a cubic yard to fill
