The object of this puzzle is to figure out what's in the cardboard box! In this box is an object that will fit through all 3 shapes shown on the puzzle: a square, a circle, and a cross. The object will completely fill all 3 shapes as it pass through, that is it will conform to the edges and leave no voids. Seems impossible! But, it isn't. Can you figure out what the object in the box looks like without opening the box? Great puzzle for all you mechanical types, engineers, draftsmen, and anyone who likes a mystery.
