Homework question?
Word does not have a limit to the number of pages, but rule-of-thumb is not
to exceed 40mb of text (ie no pictures, embedded files, etc.), who many pages
this equals depends on many factors, font size, default printer, etc.
Excel is limited to 256 worksheets, if you want more information ask in the
Excel newsgroup.
The above is for 2003 and prior, 2007 may have greater limits.
Hope this helps and within your 1 hour ;-)
