how many cf or yards are in a LA480 60inch bucket
You can get very close by multiplying PI (3.1417)
times the radius of the bucket squared
times the length (60") and then
divide by 2 since the bucket is only half a cylinder.
Then convert the cubic inches to cubic feet. 1 cubic foot equals 1728 cubic inches. 9 cubic feet equals 1 cubic yard.
Have fun.
I'm sure you meant that there are 27 cubic feet in a cubic yard.
