The formula is:

(Length x Width x Height) / 27 - All measurements in feet

example - a 10' x 10' x 6" thick patio

10 x 10 x .5 = 50 cubic feet

50 cf / 27 = 1.85 cubic yards

for round applications (post holes etc..) take the area of the circle x depth

The formula I use is 15 tons = about 12 yards.

roughly 240 square feet. Formula for figuring yardage is: (Width X Length X thickness)/27= cubic yardage of concrete. Just reverse the formula to solve for Width X Length or Square Feet. CY X 27 divided by thickness = square footage

You can't express a volume of concrete in yards.

You will need 1.23 cubic yards.

1350/depth of the concrete in feet
