You can put this solution on YOUR website! A square checkerboard contains a rows and columns of squares. One checker piece is placed in each square on the boundary of the checkerboard. If b is the number of pieces required to do this, what is one possible value of b?
================
If it's an 8 by 8 board, it's 30 checkers.
In general, if the board is n by n, it's 4n - 2
If it's m by n, tho I've never seen a board that's not square, it's 2m + 2n - 2
