At roughly 48mm per side, one kilogram of copper occupies less space than its weight might lead you to expect, giving the cube a dense, purposeful feel when lifted.\u003c\/p\u003e\u003ch3\u003eA useful benchmark for the collection\u003c\/h3\u003e\u003cp\u003eThe round kilogram makes this format especially interesting alongside other elements. Keep the mass the same and the dimensions have to change with density, so the cube itself becomes a physical comparison rather than merely a display piece. Copper adds its own warm colour and a surface that develops its own patina over time.\u003c\/p\u003e\u003cp\u003eExplore other sizes among Project Atomic’s \u003ca href=\"\/collections\/copper-cubes\"\u003ecopper cubes\u003c\/a\u003e, or compare one kilogram across \u003ca href=\"\/collections\/metal-cubes\"\u003emetal cubes in other elements\u003c\/a\u003e.
