Concept:A vertex is a corner point where three edges meet. A cube has 8 such corners.Explanation:Imagine a cube. It has 4 vertices on the top face and 4 on the bottom face. For example, the top front left, top front right, top back left, and top back right are four. Similarly, the bottom face has four more. Each vertex is formed where three edges join. No other corners exist. Therefore, the total number of vertices is 8. Common mistakes: 6 refers to faces, and 12 refers to edges.
