"Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since 1964. ...
The court dimensions.
A volleyball court is 18 m (59 ft) long and 9 m (29.5 ft) wide, divided into 9 m × 9 m halves by a one-meter (40-inch) wide net. The top of the net is 2.43 m (8 ft 0 in) above the center of the court for men's competition, and 2.24 m (7 ft 4 in) for women's competition, varied for veterans and junior competitions.
The minimum height clearance for indoor volleyball courts is 7 m (23 ft), although a clearance of 8 m (26 ft) is recommended.
A line 3 m (9.84 ft) from and parallel to the net is considered the "attack line". This "3 meter" (or "10-foot") line divides the court into "back row" and "front row" areas (also back court and front court). These are in turn divided into 3 areas each: these are numbered as follows, starting from area "1", which is the position of the serving player.
After a team gains the serve (also known as siding out), its members must rotate in a clockwise direction, with the player previously in area "2" moving to area "1" and so on, with the player from area "1" moving to area "6".
The team courts are surrounded by an area called the free zone which is a minimum of 3 meters wide and which the players may enter and play within after the service of the ball. All lines denoting the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore a part of the court or zone. If a ball comes in contact with the line, the ball is considered to be "in". An antenna is placed on each side of the net perpendicular to the sideline and is a vertical extension of the side boundary of the court. A ball passing over the net must pass completely between the antennae (or their theoretical extensions to the ceiling) without contacting them." [Volleyball. Wikipedia]

"Offensive tactics in set pieces. ...
Throw-ins[edit]
How throw-ins are best handled depends on where it is:
(1) In one's own half the aim of a throw-in may be to retain possession in order to build up the next attack. The throw may or may not go toward the opponents' goal; the most unmarked player may be a full-back who is behind the ball. Such a throw followed by a quickly taken 'switch' pass can be an effective tactic. Under pressure however, the ball is often thrown up the line, toward the opponents' goal line to gain as much ground as possible.
(2) If the thrower is unmarked, a simple tactic is to take a short throw to the feet or chest of a marked player who immediately returns the ball to the thrower.
(3) In the last third of the pitch a player with a long throw can put pressure onto the defenders by throwing the ball deep into the opponents' penalty area, resulting in somewhat similar tactics to a corner kick situation, but with the added advantage of avoiding the offside trap, as an attacking player cannot be offside from a throw in. ...
Goal kicks.
A goal kick is an important 'set piece' that will occur many times in a game and yet few teams practice it. If taken quickly the kick may be taken short to a full-back who has run into a wide position. Although this may gain little ground it retains the all-important possession of the ball. A longer kick to the midfield is more common and it is vital that the midfield unit are in a position to receive it.
Corners.
A corner kick (or "corner") is a real goal scoring opportunity and it is essential to know who is the best at taking a good corner from both the left and right side of the pitch. A good corner will be aimed high across the goal and may be 'bent' towards or away from the goal. At least one of the forwards should be on or close to the goal line when the kick is taken.
Another tactic on a corner is to let the best shooter stay in the back "trash" position and have the defence worried about those up front. The player taking the corner kick makes a small pass back to the trash shooter who has time and space to take a good shot." [Association football tactics and skills. Wikipedia]

This seating plan sample shows the stadium seat layout.
"A modern stadium (plural stadiums/ stadia) is a place or venue for (mostly) outdoor sports, concerts, or other events and consists of a field or stage either partly or completely surrounded by a structure designed to allow spectators to stand or sit and view the event. ...
Spectator areas and seating.
An "all-seater" stadium has seats for all spectators. Other stadiums are designed so that all or some spectators stand to view the event. The term "all-seater" is not common in the U.S., perhaps because very few American stadiums have sizeable standing-only sections. ...
The spectator areas of a stadium may be referred to as bleachers, especially in the U.S., or as terraces, especially in the United Kingdom, but also in some American baseball parks, as an alternative to the term tier. Originally set out for standing room only, they are now usually equipped with seating. Either way, the term originates from the step-like rows which resemble agricultural terraces. Related, but not precisely the same, is the use of the word terrace to describe a sloping portion of the outfield in a baseball park, possibly, but not necessarily for seating, but for practical or decorative purposes. ... Many stadiums make luxury suites or boxes available to patrons at high prices. These suites can accommodate fewer than 10 spectators or upwards of 30 depending on the venue. Luxury suites at events such as the Super Bowl can cost hundreds of thousands of dollars." [Stadium. Wikipedia]
