Can this calculator find the surface area of irregular or custom shapes?

No, the tool only supports a predefined list of common geometric solids such as spheres, cubes, cylinders, and cones. For irregular shapes, manual calculation or specialized software would be required.

Does the calculator show lateral surface area separately from total surface area?

Yes, for shapes like cylinders, cones, and pyramids, the calculator can display the lateral surface area—the area of the sides excluding the bases—alongside the total surface area.

Is the result affected by the units I use for input?

The calculator computes the area based on the input numbers provided; it does not automatically convert between units, so users should ensure consistent units for accurate results.

Can I save or share my calculation with others?

Yes, the tool provides a share link feature that allows users to export their current calculation and inputs to share with others or save for later reference.
