What is surface area?

Surface area is the total area of all the faces or surfaces of a three-dimensional object.

What is the surface area of a sphere?

The surface area of a sphere is SA = 4 x pi x r^2, where r is the radius.

Select a 3D shape and enter the required dimensions to calculate its total surface area. Supports cube, sphere, cylinder, and cone.
