Answer:
678.584013 cm3
Explanation:
First, take the measurement of the diameter (widest measurement you can take of the base), then measure or estimate the height. If you already have plans or schematics, just get the lenghts from there. Convert the lenght units to the same base, e.g. inches or centimeters, then follow the formula above or use our online volume of a cone calculator. The output is always in cubic units, e.g. cubic inches, cubic feet, cubic yards, cubic mm, cubic cm, cubic meters, and so on.
The cone is not as popular as some other bodies in construction and engineering, but it has its uses. One of the first examples you can think of are traffic cones, which might be filled with water or other material to keep them in place, especially in windy locations.
