Wow, those are some huge tennis balls.

anyway....

making some assumptions:

there are 3 balls in a can

the box is filled with cans in a 3by2 arrangement.

radius of one can= 2

height of can = 12 , (3 times the diameter)

volume of one can = π(2^2)(12) = 48π

so volume of 6 cans = 288π

length of box = 12 , (3 diameters)

width of box = 8 , (2 diameters

height of box = 12

volume of box = 12(8)(12) = 1152

empty space = 1152-288π or appr. 247 cubic inches.
