Yes, a cuboid has 12 edges.
Understanding Cuboids
A cuboid is a three-dimensional solid. According to the provided reference, it has the following properties:
- Faces: 6 (all rectangular)
- Vertices: 8
- Edges: 12
A cuboid also has three dimensions: length, width, and height.
Visualizing the Edges
Imagine a rectangular box. The lines where the faces of the box meet are the edges. Counting all those lines will show that there are indeed 12 of them.
Perfect Cuboids
The reference also mentions a "perfect cuboid," which is a cuboid with integer edges. This is an interesting fact, but not directly relevant to answering whether a cuboid has 12 edges. Regardless of whether the edge lengths are integers or not, the number of edges remains the same.
