How Many Edges Does a Cube Have?
Answer – A cube has a total of 12 edges.
Explanation:
A cube is a 3-dimensional figure with 6 square faces. There are multiple ways to find the number of edges in one.
Method 1: Using the number of edges per face
Every face of a cube has 4 edges, and every such edge is shared by 2 faces. Therefore, the number of edges for 6 faces will be (6 × 4) ÷ 2 = 12.
Method 2: Using the total number of vertices
Each vertex of a cube is shared by 3 edges, and each edge is linked to 2 vertices. So a total of 8 vertices will have (8 × 3) ÷ 2 = 12 edges.
Method 3: Drawing the figure and manually counting
From the above figure, it is evident that a cube has 12 edges.
