Volume Calculator

Calculate the volume of 3D shapes — sphere, cylinder, cone, cube, rectangular prism, and more.

Our free Volume Calculator lets you calculate the volume of 3D shapes — sphere, cylinder, cone, cube, rectangular prism, and more. It is built for students, teachers, engineers, and professionals who need fast, reliable math results who need fast, reliable results without installing software or creating an account.

Volume Calculator runs entirely in your browser on CalculatorsPlus — enter your values, get instant results, and copy or share your output in one click. Your data never leaves your device; we do not store inputs on any server.

Use the volume calculator to verify manual work, explore "what if" scenarios, and save time on repetitive calculations. For learning, try solving the problem by hand first, then check your answer here.

Results update in real time as you change inputs, so you can explore "what if" scenarios — adjust one variable at a time to see how it affects the outcome before committing to a purchase, plan, or decision.

This page includes step-by-step instructions, frequently asked questions, and practical tips below the calculator. Bookmark it for repeat use — many math tasks come up weekly during projects, studies, or financial planning.

Frequently Asked Questions

What 3D shapes can this calculate?
This calculator handles spheres, cubes, rectangular prisms, cylinders, cones, pyramids, and triangular prisms.
What is the volume formula for a sphere?
Volume = (4/3) × π × r³, where r is the radius. For a sphere with radius 5: V = (4/3) × π × 125 ≈ 523.6 cubic units.
How is cylinder volume calculated?
Volume = π × r² × h (area of circular base × height). A cylinder with radius 3 and height 10: V = π × 9 × 10 ≈ 282.7 cubic units.
What units does volume use?
Volume uses cubic units: cm³, m³, ft³, in³. For liquids: 1 liter = 1000 cm³, 1 gallon ≈ 3,785 cm³.
