Volume Calculator
Calculate the volume and surface area of spheres, cubes, cylinders, cones, and rectangular prisms
Frequently Asked Questions
How do I calculate the volume of a cylinder?
Multiply pi by the radius squared, then multiply by the height. The formula is V = pi * r^2 * h.
What is the difference between volume and surface area?
Volume measures the space inside a 3D shape in cubic units, while surface area measures the total area of all the outer faces in square units.
How do I calculate the volume of a cone?
Use the formula V = (1/3) * pi * r^2 * h. A cone has exactly one-third the volume of a cylinder with the same base radius and height.
