Height of cylinder, h

= 3 times the diameter of tennis balls

= 3*2.5"

= 7.5"

Diameter of cylinder, d

= diameter of tennis ball

= 2.5"

Volume of cylinder

= πd²h/4

Volume of each tennis ball, v

= 4π(d/2)³/3

Volume of three tennis balls

= 3v

= 4π(d/2)³

Interstitial space

= Volume of cylinder - volume of three balls.
