What is a Cube?
A cube is a three-dimensional geometric shape with six identical square faces, twelve equal edges, and eight vertices. It's a special case of a rectangular prism where all dimensions are equal, making it one of the most symmetrical 3D shapes.
Key Properties
- 6 Faces: All squares of equal size
- 12 Edges: All of equal length
- 8 Vertices: Corner points where edges meet
- Perfect Symmetry: Looks identical from multiple angles
Essential Formulas
Surface Area: SA = 6a²
Total area of all 6 faces
Volume: V = a³
Space inside the cube
Face Diagonal: d = a√2
Diagonal across a face
Space Diagonal: D = a√3
Diagonal through the center

Calculation Tips & Insights
✓ Key Relationships
- • Volume grows as the cube of the side length
- • Surface area grows as the square of the side length
- • Face diagonal is always √2 times the side length
- • Space diagonal is always √3 times the side length
✗ Common Mistakes
- • Confusing face diagonal with space diagonal
- • Forgetting that surface area includes all 6 faces
- • Mixing up area (square units) and volume (cubic units)
- • Using diameter instead of side length
