The International 1/4 ­ inch Rule is used for estimating lumber volume (in Boardfeet) for an 8­foot saw log.  The "Rule" generates the following  data.  Use the data to generate the quadratic formula for the International 1/4 ­ inch Rule.  Then, use the formula to find the volume of lumber in a 17 inch log.  If the log sells for 53 cents per board food and you pocket 1/3 of the proceeds, how much do you make on that 17 inch log? Log Diameter (inches) Volume (BF)         10      28.67         12      44.01         15      72.99
