Volume Calculator

Calculate volume for rectangular boxes, cubes, cylinders, spheres, cones, pyramids, hemispheres, ellipsoids, and torus.

Volume Calculator helps you volume of boxes, cubes, cylinders, spheres, cones, pyramids, prisms, hemispheres, ellipsoids, and more. Enter primary dimension, second dimension, and third dimension, review the breakdown, and use the guidance below to understand what the number means — and what it does not. What the Volume calculator does Volume Calculator is built for arithmetic, algebra, geometry, and number tools. Volume of boxes, cubes, cylinders, spheres, cones, pyramids, prisms, hemispheres, ellipsoids, and more. You enter primary dimension, second dimension, and third dimension, then Simple Calculators computes the result instantly. Results use standard school and engineering formulas that run privately in your browser. How the math works Each solid uses its standard formula — lwh for boxes, πr²h for cylinders, 4/3 πr³ for spheres, ⅓ πr²h for cones, and so on. The formula: Box: V = length × width × height. Cube: s³. Cylinder: πr²h. Sphere: (4/3)πr³. Cone: (1/3)πr²h. Switch solids to see each formula worked out with your numbers.
