How thick? Gotta have thickness to calculate cubic yards.

about 26.4 is the volume i think.......

It is all dependant on how thick the concrete is. You take the square footage and turn that into cubed feet (where the thickness comes in) if its 1" thick you multiply the square footage by.083, if its 2" thick you multiply by.17. To come up with this number you take the thickness say 3" and divide that by 12 (12 inches in a foot), so for 3 inches you get .25. So back to the question at hand, say your 30 square feet of concrete is 6 inches thick, your equation would look like this: 30 X .5 = 15. So 15 is your cubed footage. You then multiply this number by 150 which is the weight in pounds of 1 cubic foot of concrete. The number you come up with is 2,250. That is the amount in pounds of your 30 square feet of concrete assuming it is 6 inches thick.

It depends upon how thick you want the concrete. For example, if you want the concrete to be 6 inches thick, then you will need 200 cubic feet. There are 27 cubic feet per cubic yard; so divide the 200 cubic feet by 27 to get 7.4 cubic yards.

1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.

You need to specify the slab's width and the length as well.
