This is a very green question. But, I suppose if we already had all of the answers, there would be no need for the group, huh ?
I am planting a large signpost, made out of 6 X 6 pt wood. I plan to dig a hole 30 inches deep, and 30 inches square. Of course, the middle of the hole will be filled with the 6 inch square post, leaving 12 inches on all sides.
I guess the area to be actually filled with concrete then is about 30 inches deep, and 24 inches square, not counting the post.
This area seems about 10 square feet (right?) , which I believe is just over 1/3 of a yard of concrete (which would be 27 sq ft I think).
I want to use 40 lb bags of QuickCrete. Can anyone estimate how many bags I will need ?
