5,440 squares.

Step-by-step explanation:

We have been given that a chessboard has 64 squares. At a chess tournament 84 chessboards were used.

To find the number of squares on 85 chessboards, we will multiply number of squares on each chess board by number of total chess boards.

Therefore, there are 5440 squares on 85 chess boards.
