I forgot my geometry, but I know there are some real brains on here that can help.
I am building a greenhouse and the column's are set in holes augered into the soil - need to know how much concrete to plan on mixing.
Each hole is 15" in diameter and 30" deep. I can do the conversion to cubic feet and cubic yards if someone can help with the formula to get the cubic inches.
Mmmm wonder where that old geometry book is?
