You multiply 3X3X3 because each place in the code can have 3 possibilities so it's 27
All answerers - look at the example, there's an AA and BB so you can use the letters more than once!!!!!
Someone actually gave me a thumbs down - ouch - thanks schmifty for proving me right!

Now why is it that you can't use the model in the problem and add an additional letter to make 6 three letter code words? It's not a whole lot harder to do than the effort it takes to ask someone else to do your homework! sheesh
