<p>I don't really think they deal with 3D objects in Calculus AC. It's just simple mathematics: <a href="http://collegeboard.com/student/testing/ap/calculus_bc/topic.html?calcac%5B/url%5D">http://collegeboard.com/student/testing/ap/calculus_bc/topic.html?calcac</a>
integration, antiderivation. BC is a little bit harder because of those Taylor series, but still.</p>
