Calculate the volume and surface area of common 3D shapes including cubes, spheres, cylinders, and cones.
Use consistent units for all inputs. If you enter centimeters, results will be in cm³ (volume) and cm² (surface area).
Enter the radius of the base and the height. The formula is V = (1/3)πr²h.
Surface area is the total area of all surfaces of a 3D shape. It tells you how much material is needed to cover the shape.
