A cuboid has 12 edges in total.
Explanation of Edges in a Cuboid
- A cuboid is a three-dimensional shape with six rectangular faces.
- Each face has 4 edges, and since opposite faces share edges, the total count is not simply 6 faces × 4 edges = 24.
- Instead, the edges consist of 4 edges on the bottom face, 4 edges on the top face, and 4 vertical edges connecting the top and bottom faces, adding up to 12 edges total.
This systematic count confirms that a cuboid has 12 edges.
