Question 465280: How many yards of cement in 12 8" x 48" cylender with a 4"x4"x48" post in nthe middle. How many bags of cement
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
If 8 inches is the diameter of the 8" x 48" cylinders, the volume of each is
cubic inches
12V = 4608*pi cu inches =~ 14477 cubic inches.
-----------------
The volume of the post is 4*4*48 cu inches = 768 cu inches
12*768 = 9216 cubic inches
If you're putting 12 posts in 12 holes, the volume of cement for all 12 is
14477 - 9216 = 5261 cubic inches.
1 cubic yard = 36*36*36 cubic inches = 46656 cu in
----------------
5261/46656 =~ 0.113 cubic yards
