Volume Calculator - Free Online | FunToolX

Select the three-dimensional figure, enter the size parameters (length, width and height, radius, height, side length, etc.), and the tool calculates the volume and surface area. For example, the volume of a cuboid = length × width × height, the volume of a sphere = 4/3πr³, and the volume of a cylinder = πr²h.

Support complex graphics: prisms, pyramids, truncated cones, ellipsoids, etc. Each graph shows the calculation formula and derivation process. You can switch units (centimeters, meters, inches, etc.) and the results are automatically converted.

Suitable for engineering calculations (concrete dosage, container capacity), packaging design (box size), or students understanding solid geometry. The tool uses 3D sketches to display graphics to help build spatial imagination.

Volume calculator, which calculates the volume and surface area of various three-dimensional graphics, supports cuboid, sphere, cylinder, cone, pyramid, etc.
