An interactive browser-based tool for comparing the volumes of 3D geometric solids that share the same base area and height.
| Shape | Formula |
|---|---|
| Prism / Rectangular Prism | V = B × h |
| Pyramid | V = ⅓ × B × h |
| Cone | V = ⅓ × B × h |
| Sphere | V = 4/3 × π × r³ |
- Live sliders — adjust Base Area and Height and see all volumes update instantly
- Visual bar chart — proportional animated bars make the relationships immediately clear
- Key insight — Pyramid and Cone always hold exactly 1/3 the volume of a Prism with the same base and height
- Sphere bonus — radius is derived from the base area (B = πr²) for a fair comparison
