Volume Calculator — Box and Sphere
Calculate volume for a box (L×W×H) or a sphere (4/3 πr³) with the matching formula. Example: box 2×3×4 → volume 24. Browser-only solid geometry process for homework and checks.
How it works
Choose box or sphere. For a box enter L,W,H; for a sphere enter radius.
Formula
V_box=LWH; V_sphere=4/3 πr³. Notes:
- Unused fields for the other shape are ignored.
- Uses Math.PI for spheres.
- Pair with triangle / circle tools.
Example
Example: box L=2, W=3, H=4 → 24.
When to use it
- Geometry homework.
- Packaging sketch.
