Understanding Volume & Surface Area

Basic Concepts

Volume Formulas:

  • Cube: V = s³
  • Sphere: V = (4/3)πr³
  • Cylinder: V = πr²h
  • Cone: V = (1/3)πr²h
  • Square Pyramid: V = (1/3)a²h
  • Rectangular Prism: V = l×w×h

Surface Area Formulas:

  • Cube: SA = 6s²
  • Sphere: SA = 4πr²
  • Cylinder: SA = 2πr² + 2πrh
  • Cone: SA = πr² + πr√(r² + h²)
  • Square Pyramid: SA = a² + 2a√((a/2)² + h²)
  • Rectangular Prism: SA = 2(lw + lh + wh)
