Volume Calculator
Calculate the volume of cubes, spheres, cylinders, cones, pyramids, prisms, and ellipsoids from their dimensions.
Volume Calculator
Use the same unit for every dimension. The result is in those units cubed.
Volume
125 units^3
Formula
V = s^3
Surface area
150 units^2
Frequently Asked Questions about the Volume Calculator
Which volume formulas does this calculator use?
Cube V = s^3, rectangular prism V = l * w * h, sphere V = (4/3) pi r^3, cylinder V = pi r^2 h, cone V = (1/3) pi r^2 h, square pyramid V = (1/3) s^2 h, and ellipsoid V = (4/3) pi a b c.
What units should I enter?
Use any unit you like, but use the same one for every dimension. If you enter centimeters, the volume comes out in cubic centimeters (cm^3). The calculator does not convert between units.
How do I find the volume of an irregular object?
Either approximate it with the closest standard shape, split it into several shapes and add the volumes, or use water displacement: submerge the object and measure how much water it pushes aside.
What is the difference between volume and surface area?
Volume measures how much space a 3D object occupies (cubic units). Surface area measures the total area of its outer faces (square units). This calculator shows both where they are well defined.
Where are these formulas useful in real life?
Sizing tanks, aquariums, and pools, estimating concrete or soil for projects, packaging design, shipping calculations, cooking and baking conversions, and physics problems involving mass and density.
