Select a 3D shape and enter its dimensions to calculate surface area and volume instantly.
This tool calculates the total surface area and volume of common 3D shapes including cubes, spheres, cylinders, cones, and rectangular prisms.
Cube: 6 times side squared. Sphere: 4 times pi times radius squared. Cylinder: 2πr² plus 2πrh. Cone: πr² plus πrl (slant height). Prism: 2(lw+lh+wh).
Select the shape from the dropdown, enter its dimensions, and click Calculate to see the surface area and volume.
Example: A cube with side length 4 has a surface area of 96 square units and a volume of 64 cubic units.
What is slant height in a cone. It is the distance from the apex to the edge of the base circle, calculated using the Pythagorean theorem.
Does surface area include the base. Yes, this calculator includes all faces, including top and bottom bases where applicable.
