📦 Volume Calculator
Calculate the volume of 3D geometric shapes including spheres, cubes, cylinders, cones, and more.
Cube Volume
Volume = side³
Sphere Volume
Volume = (4/3) × π × radius³
Cylinder Volume
Volume = π × radius² × height

Volume Calculator FAQ
What is volume?
Volume is the amount of 3D space occupied by an object, measured in cubic units (m³, cm³, ft³, in³).
How do you calculate the volume of a sphere?
Sphere volume = (4/3) × π × radius³. For example, a sphere with radius 3 has volume (4/3) × π × 27 ≈ 113.1 cubic units.
When to Use This Calculator
Use this for cooking and baking conversions, calculating container sizes for storage or shipping, determining aquarium capacity, or solving geometry problems involving three-dimensional shapes.
Common Mistakes to Avoid
- Confusing capacity and volume — a 1-liter bottle has 1 liter of capacity, but its external volume (including the bottle material) is slightly larger.
- Using diameter instead of radius for cylinder volume — the formula uses radius (half the diameter); using diameter gives a result 4× too large.
- Forgetting to convert units — mixing centimeters and meters in the same formula produces a result that is off by a factor of 100 or 1,000.
