Formulas

  • Sphere: SA = 4πr²; V = (4/3)πr³
  • Cube: SA = 6a²; V = a³
  • Cuboid: SA = 2(lw + lh + wh); V = lwh
  • Cylinder: SA = 2πr(r + h); lateral = 2πrh; V = πr²h
  • Cone: SA = πr(r + s), where s = √(r² + h²); V = (1/3)πr²h
  • Square pyramid: SA = a² + 2a·√((a/2)² + h²); V = a²h/3
  • Hemisphere: SA = 3πr² (curved 2πr² + base πr²); V = (2/3)πr³
  • Capsule: SA = 2πr(2r + h); V = πr²h + (4/3)πr³
