Question: How did the box get out of the cement in part 3 and into a pillar in part 4?
Answer:Not sure why you submitted this question for the eighth film in the series. But regardless, that's just a bit of what's called "retroactive continuity," which is a term for when a movie either changes or ignores things from previous films. Rather than having the box be in the cement floor, it was relocated to a cement pillar. This change was presumably just because the writer or director thought it would look more dramatic for it to be ripped out of a pillar as opposed to being just dug up from the floor.
