A man has a window that measures 12 X 12 but does not let enough light in. so he saws around the window and has a window that measures 12 x 12 but lets exactly as much light in. what did he do?
The original window was diamond-shaped (i.e., with each side at a 45-degree angle to horizontal); he replaced it with a square window (i.e., with sides vertical and horizontal).
