According to the table above one cubic yard of concrete placed at a thickness of 5-inches covers 65 square feet. Multiply the width times the length times the height W L H or use our volume calculator to find the cubic yardage. If the diameter is known then divide the diameter by 2 to get the radius.
Input length width and depth of the area.
If you can determine the area of your concrete project length x width for rectangular projects and know the thickness of the slab you can use the information in the Concrete Volume Calculator below to determine how much concrete you need.
