# Volume of a frustum Calculator

## Calculates the volume of a frustum given the base and top areas, and height. | ||

- Purpose of use
- Used to calculate the volume of back fill for a underground tank basin with sloped walls.

- Purpose of use
- Calculation of detention pond volume

- Purpose of use
- Calculation of pan's volume while cooking
- Comment/Request
- Provide an option to input radius/diameter of base and top instead of base and top surface area to make it easier.

- Purpose of use
- Volume of a Storm Water Pond to provide Fire Flow
- Comment/Request
- This was very useful. Particularly for a pond where there is a requirement to the angle of the side to change at a certain depth. I used the calculator twice and was able to show the engineer did not have enough water for fire flow and that increasing the depth of the pond by one foot would provide the required water. And I learned a new word. :)

- Purpose of use
- volume of excavation for footings; cut is sloping at 45 deg. thanks from Philippines

- Comment/Request
- I am wondering why this formula does not give quite the same result as V = h/6 x (Atop + 4(Amiddle) + Abottom), another widely accepted volume formula for pyramidal prismoids - ? The results are close, but not identical as expected.

- Purpose of use
- Calculate volume of cut and fill

- Purpose of use
- engineering applications
- Comment/Request
- volume of frustum can be calculated by this formula when there is a relationship between the dimensions of bases , that if divide every length of one base side on the other trans it we will gate same value , which mean that the inclined side of frustum must meet each other in one point ( pyramid head ) , so the question is : if we have a frustum but it is not a part of pyramid , how can we calculate it's volume ?
