How to Use This Calculator

Select the 3D shape from the dropdown (cube, sphere, cylinder, cone, or rectangular pyramid).
Enter the required dimensions — for example, radius and height for a cylinder.
Total Surface Area includes all faces; Lateral Surface Area excludes the base(s).
Key formulas: sphere SA = 4πr²; cylinder SA = 2πr² + 2πrh; cone SA = πr² + πrl (where l is slant height).
The pie chart shows the contribution of each face (e.g., base vs. lateral) to total surface area.
Surface area is relevant for painting, coating, heat transfer, and packaging design problems.
