Volume Calculator

Calculate volume and surface area of spheres, cylinders, cones, and other 3D shapes

About this calculator

The Volume Calculator computes the volume and surface area of common 3D shapes including cubes, rectangular prisms, spheres, cylinders, cones, and square pyramids. Enter the dimensions to instantly see both measurements with clear formulas. Essential for geometry homework, engineering calculations, and estimating material quantities.

How to use the Volume Calculator calculator

  1. Enter the measurements you know into the input fields.
  2. Read the computed properties — they update instantly as you type.
  3. Compare the diagram with your figure to confirm the setup is right.
  4. Copy the page URL to share the exact calculation.

Common examples

  • Cube with side 4 cm → Volume = 64 cm³, Surface area = 96 cm²
  • Rectangular prism 5 × 3 × 2 m → Volume = 30 m³, Surface area = 62 m²
  • Sphere with radius 6 cm → Volume ≈ 904.78 cm³, Surface area ≈ 452.39 cm²
  • Cylinder with radius 3 cm, height 10 cm → Volume ≈ 282.74 cm³, Surface area ≈ 245.04 cm²
  • Cone with radius 5 cm, height 12 cm → Volume ≈ 314.16 cm³, Surface area ≈ 282.74 cm²

Frequently asked questions

How does the Volume Calculator calculator work?

Enter the known measurements of your figure and the calculator applies the standard geometric formulas to find the remaining properties, alongside a diagram that reflects your numbers. All values are computed with high-precision arithmetic.

When would I use the Volume Calculator calculator?

It helps with geometry homework, technical drawing, construction and DIY layout, and any situation where you know some measurements of a shape and need the rest.

How accurate are the results?

Formulas are evaluated at 30 significant digits of precision internally, including roots and trigonometric functions. Displayed values are rounded for readability, but the underlying computation does not accumulate floating-point drift.

Can I share a specific calculation with someone else?

Yes. Every value you enter updates the URL, so copying the address bar and sharing the link reopens the exact same figure and results for whoever clicks it.
