How could you use cubes to act out a problem

Well each cube could either represent 1 or you could use the colors to represent multiple numbers. like red could be 10, blue is 20 etc..

It is useful for historians to write narratives so that history can be passed on from their point of view.  think about a story being told in third person, then think about it again being told in first person, by someone who actually experienced the event.
