A chessboard with an area of 64 square inches will have dimensions that can be determined by taking the square root of the area.

The area of a square is given by the formula:
\[ \text{Area} = \text{side}^2 \]

So for Kai's chessboard:
\[ 64 = \text{side}^2 \]

Taking the square root of both sides, we get:
\[ \text{side} = \sqrt{64} = 8 \]

This means there are 8 pieces of wood along each side of the chessboard.

Therefore, the correct answer is:
**C. 8 pieces of wood**.
