Have you checked whether the page already ranks on page one for the main term? PAA boxes mostly pull from pages that already rank well, so if it doesn't, that's the first job. If it does: take the actual PAA questions, put each one as a subheading, and answer it in the first two sentences underneath, plainly, before any detail. It's easy to maintain because you're just adding short sections to pages you already have.
