A visual for Surface Area and Volume

A student discovered this today.  It is a nice little visualization to see and feel the difference between Surface Area and Volume:

Make a 3d object out of multilink cubes with lots of different colors.

How many cubes did you use?  That is the Volume (6 in the diagram).

How many squares do you see on the outside?  That is the Surface Area (22 in the diagram).
