About this tool
Calculate the volume and surface area of cubes, boxes, cylinders, spheres, cones and pyramids.
Cube a³, box a·b·h, cylinder πr²h, sphere 4/3·πr³, cone πr²h/3, square pyramid a²h/3, hemisphere 2/3·πr³.
Formula: V = πr²h · V = 4/3·πr³
Example: Shape = Cylinder → Volume = 282.743339, Surface area = 245.044227.
Use the same unit for every length; volume is in that unit cubed. Surface areas of the cone and hemisphere include the base.
