About Surface Area Calculations
Surface area is the total area of all the faces or surfaces of a 3D object. It's important in various fields including engineering, architecture, and manufacturing for determining material requirements, heat transfer, and other physical properties.
Common Applications:
- • Material cost estimation
- • Heat transfer calculations
- • Paint and coating requirements
- • Packaging design
- • Architectural planning
- • Manufacturing processes
Key Formulas:
- • Sphere: 4πr²
- • Cone: πr(r + l) where l = √(r² + h²)
- • Cube: 6a²
- • Cylinder: 2πr(r + h)
- • Rectangular Prism: 2(lw + lh + wh)
- • Capsule: 2πr(2r + h_cylinder)
