I know this is an academic question, but maybe someone will know if I am right. Here is the question

Suppose a data warehouse has four dimensions and two measures.

If each dimension has five levels (including all), such as student < major < status < university < all, how many cuboids will this cube contain (including the base and apex cubes)?




The formula I found in the book states to multiply (from 1 to n) (Li + 1). If I use 4 levels (exclude all) with 4 dimensions, then I get

4^4 = 256 cubes

Is this correct?

Thanks,
Michael
