You should stand behind the line, to serve a volleyball. If you put one of your legs over the line, the serve won't count.
If you are playing on an indoor court than you need to stand just behind the line.
The back line is the line going left to right (the length). It is also known as the second 10 foot line.
The attack line is 10 feet from the center line.
You just need to be behind the end line.
The baseline in volleyball is where you would serve from. Or if you don't serve that far back, it is considered the out line. The farthest line from the net.
Nine meters - 3 meters from the net, parallel to it is the attack line, which splits the court into two 'courts' - front court and back court, also known as front row and back row, respectively.
if you mean how far away form the end line is the 18 yard line, it is 18 yards from the end line! sort of self explanatory really!
