A standard chessboard does not have any chairs; it consists of 64 squares arranged in an 8x8 grid. However, if you are referring to a chess setup in a tournament or casual play, the number of chairs would depend on the number of players and spectators present, typically one chair per player at the board.
If you have 65 chairs with five chairs in each row, you would have a total of 13 rows. This can be calculated by dividing the total number of chairs (65) by the number of chairs in each row (5). The result of 65 divided by 5 is 13 rows.
