A cube has 12 edges.

Explanation:

• A cube has 6 faces.
• Each face is a square with 4 edges.
• However, each edge is shared by 2 faces.
• So, total edges = (6 faces × 4 edges per face) ÷ 2 = 12 edges.

If you want to visualize it, think of a cube as having:

• 4 edges along the top square,
• 4 edges along the bottom square,
• and 4 vertical edges connecting the top and bottom squares.

Total: 4 + 4 + 4 = 12 edges.
