The room is 6480 cubic feet. If 192 tennis balls fit in (3 feet) cubed, that's 27 cubic feet and 46,080 tennis balls fit in 6480 cubic feet.
Since a tennis ball has a diameter that is greater than 2 inches, the answer is 0.

241920 in^3 == typical minivan cargo volume (V) 17.576 in^3 == volume of a cube surrounding a tennis ball (v) 13764 == V/v = number of tennis ball sized cubes to fit into the cargo space of a minivan
You only need shorts that can fit tennis balls in them (must be able to put two in), and either a polo shirt or an athletic shirt.

It depends on the net and the car. If you drive a Smart Car, there's probably no tennis rebound net that will fit inside. If you have a more common car like a Focus or a Corolla, the Gamma Rebound Net should fit. It collapses down to a 3 1/2 ft diameter.
