  • How many balls do I need for my ball pit?

    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.
