I think I understand:

1. When I look at your urns they are not cylinders.

2. The inside volume is a more complex shape.

3. Your method of using a cross section of the inside volume and focusing on half makes sense.
—> a. Calculating the area of a half cross section and dividing by the height gives you a representative radius.
—> b. While representative, this radius estimate will not be accurate, but close.
—> c. Using that representative radius and the formula for the volume of a cylinder will also be close, but not accurate.


1. How accurate do you need to be?
—> a. Is an extra cubic inch (or 3) okay?

2. Are you trying to determine the volume before making the urn or after it is completed?


1. I would suggest breaking the cross section into layers and using an average radius for each layer will be more accurate.
—> a. More layers will be more accurate.

2. You could try the layering technique a couple times with decreasing layer height (more layers) and see how the answer converges.
—> a. This may help you determine how many layers are required for your desired accuracy.
