Volume Calculator
A volume calculator finds a 3D solid’s volume and surface area from its dimensions. Toolverge covers cube, sphere, and cylinder — the three most-searched solids — using the standard geometric formulas, and pairs with the Geometry Calculator’s 2D shapes for the rest of the "area/volume calculator" search category.
How it works
- Choose a solid: cube, sphere, or cylinder.
- Enter its dimensions (side, radius, or radius + height).
- Read the volume and surface area on the tape.
Formula Cube: V=s³, SA=6s² · Sphere: V=(4/3)πr³, SA=4πr² · Cylinder: V=πr²h, SA=2πr(r+h)
Frequently asked questions
How do I find the volume of a cylinder?
Multiply the circular base area by the height: V = πr²h, where r is the radius and h is the height.
What units does this use?
Whatever unit you enter dimensions in — the volume comes out in that unit cubed, and surface area in that unit squared.
How is a sphere’s volume different from its surface area formula?
Volume is (4/3)πr³ (cubic — how much space it fills); surface area is 4πr² (square — how much material would wrap it).
Does this handle a cone or pyramid?
Not yet — only cube, sphere, and cylinder are covered today.
