About this calculator
A volume calculator finds how much space a 3D shape holds. Choose the shape and enter its dimensions: a box is length × width × height, a cylinder is π × radius² × height, a sphere is 4/3 × π × radius³, and a cone is 1/3 × π × radius² × height. Only the fields the chosen shape needs are used.
Frequently asked questions
What is the volume of a cylinder?
Volume = π × radius² × height. A cylinder with radius 2 and height 4 holds π × 4 × 4 ≈ 50.27.
What is the formula for the volume of a sphere?
Volume = 4/3 × π × radius³. A sphere of radius 3 holds 4/3 × π × 27 ≈ 113.1.
