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
Trying to size water storage pond at a refinery
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.

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 ?
