Bill has 120 pecan trees that yielded 45 pounds of pecans per tree. Three-fourths of the pecans are sold as shelled nuts. A storm damaged four trees, which he cut into logs. He had four logs 12 feet long with a 32-inch diameter at the small end and three logs 8 feet long with a 22-inch diameter at the small end. He used the Doyle log rule to find the approximate number of board feet of usable lumber in the logs.
Doyle log rule formula:

d is the diameter of the small end of the log, in.
l is the length of the log, ft.
