In the case of the 3-box form, there is a "box" delineating a separate volume from the a-pillar forward, a second box comprising the passenger volume, and third box comprising the trunk area — e.g., a Sedan. The equivalent French term is volume, which you will sometimes see used by the British: "3-volume form".
