Compute the volume and surface area of spheres, cylinders, cones, rectangular prisms, and regular prisms. Ideal for architecture, fabrication, education, and lab work.
Your inputs sync to the query string, so you can share or reopen exact calculations on any device.
FAQ
How should I handle units?
Use the same unit for every dimension. Volume is returned in cubic units and surface area in square units.
Does the shared URL keep my inputs?
Yes. Values are stored in the query string so anyone opening the link will see the same setup.
How it’s calculated
- Sphere: V = 4/3·π·r³ and A = 4·π·r².
- Cylinder: V = π·r²·h and A = 2·π·r·(r+h).
- Cone: V = 1/3·π·r²·h and A = π·r·(r+ℓ), where ℓ is the slant height.
- Prism: V = base area × height; surface area sums all faces.
- Outputs use square/cubic units consistent with your inputs.
- Symbols: V = volume, A = surface area, B = base area, Aₗ = lateral area, d = space diagonal, ℓ = slant height.
How it's calculated
- Uses standard formulas for volume/surface area of sphere, cylinder, cone, prism/cuboid.
- Inputs validated as non‑negative; units carried consistently in output.
- Intermediate steps show substituted values when helpful.
- Share URL preserves parameters.
