A cube in 3D has 12 edges.
A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Understanding its properties, including the number of edges, is fundamental in geometry.
Based on the provided reference, it is explicitly stated that a cube has 12 edges. Each edge is a line segment where two faces of the cube meet. Visualizing a cube or examining a physical model readily confirms this count.
