Will a medium box (46x46x41 cm) fit in a space?

A medium box measuring 18 in × 18 in × 16 in fits in a space, with about 1 ft 2.5 in to spare at the tightest point. The binding dimension is width: in its best-fitting orientation, the width is what comes closest to the limit, and it still clears. We checked every orientation and confirmed at least one places the medium box fully inside without compression or disassembly. That margin already subtracts a 1.5 in handling allowance, so it reflects a realistic load rather than a paper-thin theoretical fit. One caveat: item is rigid and cannot be compressed, bent, or disassembled.
