Compute the volume of a pyramid-shaped earthwork from base area and height.
输入底面积 A 与高 h,求锥体体积。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Pyramid and cone volume | V = (1/3) · A · h, where A is the base area and h the height | Euclid, Elements, Book XII, Proposition 10 |
| Relation to the prism | One third of a prism with the same base and height | Euclid, Elements, Book XII |
| Prismoidal formula | V = h/6 · ( A1 + 4·A_m + A2 ), where A_m is the mid-section area | GB 50026-2020, Code for engineering surveying (earthwork volume) |
| Use in earthwork | Used for conical stockpiles, spoil heaps and pit excavation volumes | GB 50026-2020, Code for engineering surveying |
