@howie_hua @LorrieTemple 37 small holes + the man hole makes 38
@howie_hua (3+3+3)*4 + 1 9*4+1 36+1 37
@howie_hua I counted 8 on the top and bottom rows and 8x2 is 16 plus the middle rows which is 7 columns of 3 and 7^3 21 so 21 plus 16 is 37! Plus the entire sewer is a hole so 38.
@howie_hua Counted each hole - one at a time. Took a screenshot and marked off each hole. 37 little holes. #mathisfun
@howie_hua I'm gonna have more fun with other answers than mine. I thought of a chessboard and immediately started seeing ranks and files and had trouble choosing a method. I can visualize several partitions but am having trouble picking one. (1/2)
