Also known as 3-hypercube, regular hexahedron, 3-cube

مجسم ثلاثي الأبعاد محدد بستة أوجه مربعة

AI overview

A cube is a three-dimensional shape made up of six identical square faces connected by twelve equal-length edges, with eight corners where edges meet. Cubes are important in geometry and mathematics because they serve as a fundamental example of a polyhedron and appear frequently in everyday objects, from dice to building blocks.
