what is the equation to figure out how many yards of concrete are needed if you have the square footage? example: 840 sqft, 3" thick= how many yards?

based on 2x4 forms , divide your area by 80 .... 10.5 yards...

3" your kidding right you need 4" divide your SQ FT by80 and you will have it

4" is better. Length x width x thickness.....divide by 27 (27 cubic feet in a yard) Don't forget control joints.....
Example 10' x 15' x .33' (for four inches thick) four inches is a third of a foot. That's 49.5 cubic feet. Divide by 27 = 1.83 yards (Probably order 2)
A 2x4 which is commonly used for forms is 3.5" high when laid on its side. But its better to have a little extra than not enough so figure 4". Always round up... the grading is not always perfectly flat and level.
Good luck....
