Surface Area Calculator

Calculate the surface area of 3D shapes — cube, sphere, cylinder, cone, rectangular prism, and more.

Using the Surface Area Calculator

The surface area is the total area that the surface of an object occupies. This tool is essential for determining how much paint, wrapping, or material is needed to cover a 3D object, supporting all standard geometric solids.

How it Works

Choose the 3D solid from the menu.

Input the necessary dimensions.

Review the "Total Surface Area" result.

Check the formula breakdown to see how the lateral and base areas are combined.
