At 49mm per side, the cube shows exactly how much space solid niobium needs to reach one kilogram. That makes it more than a larger version of the smaller cubes: it becomes a reference object for comparing density across different elements.\u003c\/p\u003e\u003ch3\u003eCompare size, keep weight constant\u003c\/h3\u003e\u003cp\u003eNiobium's density of 8.57g\/cm³ places its one-kilogram cube between lighter and much denser metals in physical size. Put equal-mass cubes together and that difference is immediately visible, even before you pick anything up. The simple chamfered form keeps the comparison honest: same basic geometry, same kilogram, different volume.
