Okay, this is driving me nuts. I looked through my AP Stylebook (2006) and couldn't find how to write this: 875,655 square feet. As I wrote it, it struck me to look it up, didn't seem right.

My (news) story is due soon and I like to have as clean of a copy as possible when I turn it in (so I won't look like an idiot!). So could'ya help me out?

Do I write out "square feet" or "sq ft" or somethin' else?
