๐ฆ 3D Shape Volume Calculator
Volume125
Surface area150
Select a common 3D shape โ cube, rectangular box, sphere, cylinder, or cone โ enter its dimensions, and instantly get its volume and surface area. Useful for schoolwork, DIY projects, and estimating packaging sizes.
How to use
- Select the shape you want to calculate (cube, box, sphere, cylinder, or cone).
- Enter the dimensions for that shape (side length, radius, height, etc.).
- The volume and surface area are calculated automatically.
FAQ
What units should I use?
This calculator is unit-agnostic. Enter all dimensions in the same unit (e.g. cm), and the results will be in that unit cubed (volume) and squared (surface area).
What does the cone's surface area include?
It's the total surface area: the area of the circular base plus the lateral (side) surface area.
Where do these formulas come from?
These are the standard geometry formulas taught in school (e.g. sphere volume = 4/3 ร ฯ ร radiusยณ).
