The formula is: Length (L) x Width (W) x Depth (D) = Cubic volume, then divide by 7 to determine the number of 500 ball cases you need. Example: 8' (L) x 8' (W) x 2' (D) = 128 cubic feet of volume then divide by 7 (cu. ft. of balls in a case of 500) the answer is 18.29. Thus, you will need 18 or 19 cases to fill your ballpit 2 feet deep ... · 1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill.
