Think you know how many Prince tennis balls it takes to fill up a 2' x 2' x 7' container? This is the same container currently on display in Rockefeller Center in New York City as part of the Wimbledon in NYC event.
So take a look, and submit your guess to win! All guesses must be submitted HERE
The person closest to guessing the exact number of balls, without going over, will receive a free Prince EXO3 racquet, premium racquet bag and autographed racquet from Maria Sharapova. (US promotion only)
Good luck, enjoy Wimbledon and be sure to let your friends and other tennis players know to submit their guess too!
