I know that a compound adjective preceding a noun would require hyphenation in most circumstances; however, this particular phrasing has me doubting myself and I'd just like some clarification, if possible.
With the following, if this comes at the end of a sentence, should it be hyphenated?
'...1.65 million square feet.'
My gut is telling me no, because there is no noun following it, but I'm not 100% certain.
A full-sentence example for this query would be:
'The total build of the structure covered 1.65 million square feet.'
It's the '1.65 million square feet' section of that sentence that I'm querying.
Sorry for any confusion my initial post created.
