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
