Volume usually diverges faster than intuition
Even when the silhouettes feel manageable, total occupied space can separate quickly. A rough volume estimate puts one loaf of bread at about 127 car key fobs, which is why the bigger object can feel more dominant than a single dimension suggests.
Key insight
