how do i figue out how to do arrays and an expanded algorithm

Since this is not my area of expertise, I searched Google under the key words "doing arrays expanded algorithm " to get these possible sources:
http://www.google.com/search?client=safari&rls=en&q=doing+arrays+expanded+algorithm&ie=UTF8&oe=UTF8
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/. 
My son is doing expanded algorithm and the problem is

the problem is there are cubes underneath the problem for him to fill in but ive tried every way I can think of to solve this problem and the answer just doesnt fit into these cubes, any suggestion?
