Multiply the width times the length times the height W L H or use our volume calculator to find the cubic yardage.
To do so divide the cubic footage by 27 to get the yards of concrete needed.
Convert the volume to cubic yards from cubic feet. The first step is 1 yd. Learning how to calculate the amount of concrete needed is easy when using our concrete formula and online concrete calculator. Calculate the volume of your area after determining its shape see the examples below by multiplying it with the thickness of the concrete.
