Surface Area Formulas
| Shape | Formula |
|---|
| Sphere | SA = 4πr² |
| Cube | SA = 6a² |
| Rectangular Box | SA = 2(lw + lh + wh) |
| Cylinder | SA = 2πr(r + h) |
| Cone | SA = πr(r + l), l = √(r² + h²) |
| Capsule | SA = 2πr(2r + h) |
| Conical Frustum | SA = π(R + r)l + π(R² + r²), l = √((R−r)² + h²) |
| Square Pyramid | SA = a² + 2al, l = √(h² + (a/2)²) |
