Kai is making a chessboard using pieces of wood that measure 1 square inch.

Question

When he finishes, the chessboard will have an area of 64 square inches.
How many pieces of wood should he put along each side?
64 pieces of wood
642 pieces of wood
8 pieces of wood
82 pieces of wood

Answer 1

A chessboard that has an area of 64 square inches would be \(8 \times 8\), since \(8 \times 8 = 64\).

Since each square on the chessboard measures 1 square inch, he will need 8 pieces of wood along each side of the chessboard.

Therefore, the answer is:

8 pieces of wood.
