Approximately 44-45 yards would be required to place a 4" thick slab on a 3000SF area. There are 27 cubic feet in a cubic yard, and at 4" thick there is 3 square feet of coverage in a cubic foot:
[# SF] x [# inches thick / 12 inches per foot] / [27 cubic feet per yard]
3000 x 4/12 / 27 = 37 yards
Now, that's ideal. Your surface won't quite be level, so figure on an extra 10-15% for the low spots (you don't want anywhere to be less than 4"). Then figure an extra 5-10% for waste and shortage. You'll drop a bit here and there, and you'll never get all the concrete out of a mixer. You definitely don't want to order too little, so about 45 yards is what you'll need.
Don't forget to cut your slab every 8-10 feet (usually ~1.5" deep with a special piece of equipment called a Soff-cut saw) while it's still curing or you'll get random cracking. Also, make sure you get some structural fibers added to the mix, or use welded wire reinforcement (called WWR of WWF) - to keep any cracks that do form from growing and make the slab more durable.

How many yards of concrete will you need for a 3000 sq ft house slab?
40 yards.
How much concrete to cover 3000 sq ft 6 inches thick?
To calculate the amount of concrete needed to cover 3,000 square feet at a thickness of 6 inches, first convert the thickness from inches to feet: 6 inches is 0.5 feet. Then, multiply the area by the thickness: 3,000 sq ft × 0.5 ft = 1,500 cubic feet of concrete. To convert cubic feet to cubic yards (since concrete is typically measured in cubic yards), divide by 27: 1,500 cu ft ÷ 27 = approximately 55.56 cubic yards. Therefore, you will need about 56 cubic yards of concrete.
How do you calculate the amount of concrete to order for your driveway if the driveway is 20' wide 40' long and 3 thick?
Multiply length by width by depth (in feet). Divide that number of square feet by 27 to get cubic yards and then allow for a little extra. (20 X 40 X .25 = 200 / 27 = 7.4 yards) The answer is spot on correct however with 30 years of concrete experience I would not recommend a 3 inch thick slab unless you have very light vehicles. Our normal pour for garage slabs or driveways is a 4 inch pour using 3000 psi concrete with air entraining. This will give you a slab that you can depend on for delivery vehicles and others that may use your drive.
