Multiply the thickness by the length by the width. This will give you the volume of concrete needed.

Hi,

In addition to the calculated volume, you'll need to consider +10%, to cover normal wastage,

Good luck!

Length x Width x Thickness (all in feet) will get you the volume in cubic feet. Divide that by 27 for cubic yards.

when figuring concrete calculations just as every one said length x width x thickness devided by 27 will give you how many yards.
Thickness may confuse you if you are pouring a slab 4" thick use .33 If you want it 6" thick use .50 dont forget your rat wall if its something other than a slab.
so if your going to to pour a patio 12'x12'x4" thick type it in like this 12 x 12 x .33 devided by 27 equalls 1.76 cu. yards and then give yourself some fudge factor. good luck
