Both service boxes are used, but in a slightly different order than normal play. The player whose turn it would usually be to serve gets to serve first; he serves one point from the deuce court. After this, the players switch boxes and starting with the serving player's opponent, each player gets to serve two points in a row. The players switch service boxes after each point, just as in a regular game. They also must switch sides of the court every six total points (e.g., if the score is 4-2, the players must switch sides).
Tiebreakers are scored numerically: 1, 2, 3, etc., not"15," "30," "40."
Set tiebreakers (that is, tiebreakers played to determine the winner of a 6-6 set) are usually played first to 7 points by a margin of two; if the score should turn out to be 7-6 in a tiebreaker, the players must continue playing until one is ahead by two points (8-6, 12-10, and 24-22 are all valid ending tiebreak scores).
The service box is located on a tennis court near the net, on either side of the court. It is the area where the server must hit the ball during a serve.
To gain a strategic advantage over your opponent in tennis, the ball should be served to the corners of the service box, aiming for the backhand side of your opponent if they have a weaker backhand. This can force your opponent to move more and make it harder for them to return the serve effectively.
One of the boys leaves the ball in the box and takes the box with him.
Some special rules made in tennis is that if the ball bounces on your box you will be out.
As long as it lands in the correct box, it's considered a "let."

No
Since a tennis ball has a diameter that is greater than 2 inches, the answer is 0.
In tennis, you serve the ball from behind the baseline into the diagonally opposite service box on the other side of the net.
The umpire or line judge simply calls the ball out. They don't have to explain anything, but occassionally a player may ask the chair umpire to confirm the call. In major tournaments, there may be a challenge system in place that allows players to challenge a chair umpire's or line judge's call using replay cameras, but even then, the umpire doesn't have to explain anything, they just say whether the point will be replayed or they call a new score.
