Will the pile be placed at the bottom of the box?

The lower tip of the pile may or may not touch the bottom of the box. It is not critical that your pile touches or not touches the bottom of the box. You are not allowed to “attach” or “hook”  or glue the pile to the box.  If your pile is slightly longer than the height of the box (18.25 in ±0.5 in), there will not be any penalty.
