I want to add compost starter to my compost holder. The holder is shaped like a barrel with a tapered top. The starter is added by cups depending on the number of cubic feet. I have no idea how to calculate how many cubic feet there are in my compost holder. Any help would be appreciated. thanks.

If the barrel is evenly tapered evenly then you can find the volume by measuring it's height in feet and the diameter (width) of the barrel across it's middle, also in feet. Then volume in cubic feet would be 3.14 * (diameter/2)^2 * height.
