Question

a chessboard has 64 squares at a chess tournament 84 chessboards were used how many squares are there on 85 chessboards

Answer 1

there are 5376 squares on all of the chessboards because 84 x 64= 5376

Answer 2

5,440 squares.

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.

`\text{The number of squares on 85 chessboards}=\frac{\text{64 squares}}{\text{Chess board}}* \text{85 chess boards}`

`\text{The number of squares on 85 chessboards}=\text{64 squares}* 85`

`\text{The number of squares on 85 chessboards}=5440\text{ squares}`

Therefore, there are 5440 squares on 85 chess boards.
