📦 Volume Calculator
Calculate volume of cubes, spheres, cylinders & more
How Volume Calculation Works
- 1Select the 3D shape you want to calculate.
- 2Enter the required dimensions (side, radius, height, etc.).
- 3The calculator applies the correct volume formula.
- 4Surface area is also calculated for each shape.
- 5For spheres: V = (4/3)πr³. For cylinders: V = πr²h.

Frequently Asked Questions
What units does volume use?
Volume is in cubic units. If measurements are in centimeters, volume is in cm³. If in inches, it is in in³.
What is the volume of a cone?
The volume of a cone is V = (1/3)πr²h — exactly one-third of the volume of a cylinder with the same base and height.
Does this calculate surface area too?
Yes. Both volume and surface area are calculated for every shape.
