A cube, regardless of how "long" it is (assuming this refers to its proportions remaining cubical despite changes in scale), always has 12 edges.
To understand why, consider the components that make up a cube:
- Faces: A cube has 6 square faces.
- Vertices: A cube has 8 vertices (corners).
- Edges: Edges are the line segments where two faces meet.
The key is that the fundamental structure of a cube defines its number of edges. "Long" simply implies that the cube might be stretched or elongated in one dimension compared to a standard cube where all sides are equal, but it maintains the same basic geometric properties. The number of faces (6), vertices (8), and importantly, the number of edges (12), remains unchanged.
Therefore, a "long cube" still has 12 edges.
