If I'm told that a box's height is 10 and that the thickness is 5, should I
- Assume that the box's real height is 15.
- Assume that the box's content height is actually 5, and due to the thickness it is said that the total box height is 10
Edit: Think of it as a cardboard box. The cardboard material used can have certain thickness. And the thicker, the "bigger" the box seems to be.
