Fill in the blanks :
The number of edges in a cube is …….. .

Answer

To solve the question, "The number of edges in a cube is ……..", we can follow these steps:

### Step-by-Step Solution:

1. **Understand what a cube is**: A cube is a three-dimensional geometric shape with six square faces, twelve edges, and eight vertices.

2. **Identify the edges**: Edges are the line segments where two faces of the cube meet. In a cube, each face has four edges.

3. **Count the edges**:
- Each of the 6 faces has 4 edges.
- However, each edge is shared between two faces, so we need to be careful not to double count.
- The formula to find the number of edges in a cube is:
\[ \text{Number of edges} = 12 \]

4. **Fill in the blank**: Therefore, we can conclude that the number of edges in a cube is 12.

### Final Answer:
The number of edges in a cube is **12**.
