Will BISSA Shoe cabinet with 3 compartments, white, 19 1/4x11x53 1/8 " fit in a BMW X3 2022?

The X3 gives you a wide, level cargo bay. The hatch opens 44⅛ inches across and 31⅛ inches tall, and the floor holds 43¼ inches at its narrowest, so wide boxes that snag in smaller SUVs slide through here. Length is the catch: 37⅜ inches behind the seats, 70⅛ inches once they fold, a gain of +32⅝ inches. The floor sits level with the 27½ inch liftover, no drop on the far side, so a heavy carton pushes straight in. Save long flat-packs for seats-down trips; upright, the bay favors short, wide, stackable boxes. Slide heavy loads in across the sill and spare your back.

BISSA ships as a single flat box, 54¼″ × 16¾″ × 3″, and it weighs 45 lb 15 oz. At 3″ thick it slides into gaps a built cabinet never would, so the thickness is not your problem. The length is. At 54¼″ you need a trunk that measures long enough on the floor, or one rear seat folded so the box can run forward between the seats. Most hatchbacks take it with the seats down, and any wagon or SUV swallows it flat. Lift it on edge with two hands, and rest it on a long edge rather than a corner, because 45 lb 15 oz of flat pack lands hard and the corners split first.
