Question Concerning Biblio

I know that this is probably a little late to be asking this, but does the essay have to be an exact amount of pages or words? I've being assuming that it needs to be ten pages, but I was looking at the syllabus and no page length is mention. Have I just been thinking it needs to be ten pages because we need ten sources? It seems like this was clarified in class a couple of weeks ago and I apparently wasn't paying very close attention. I'm going to assume that Dr. Rogers is mostly concerned with quality verses quantity and whether or not I cover everything that needs to be mentioned. Is this a safe assumption???
