Respuesta :
there are 5376 squares on all of the chessboards because 84 x 64= 5376
Answer:
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.
[tex]\text{The number of squares on 85 chessboards}=\frac{\text{64 squares}}{\text{Chess board}}\times \text{85 chess boards}[/tex]
[tex]\text{The number of squares on 85 chessboards}=\text{64 squares}\times 85[/tex]
[tex]\text{The number of squares on 85 chessboards}=5440\text{ squares}[/tex]
Therefore, there are 5440 squares on 85 chess boards.
