   LawnGreen Box   RosyBrown Box   DarkOrchid Box   DarkBlue Box   SkyBlue Box   RoyalBlue Box   Lavender Box   MidnightBlue Box   MediumSpringGreen Box  times     Black Box Box  equals     DeepSkyBlue Box   LawnGreen Box   RosyBrown Box   DarkOrchid Box   DarkBlue Box   SkyBlue Box   RoyalBlue Box   Lavender Box   MidnightBlue Box

We start with nine boxes, multiply by one box, and now still have nine boxes.
