The total volume of a dumpster is measured in cubic yards (yd³), where as the exterior of the dumpster is measures in feet. The exterior dimensions are the length, width, and height. By multiplying the exterior dimensions (in feet), you will get the volume in cubic feet. In order to convert cubic feet to cubic yards, you must divide the volume in cubic feet by 27.
