	 	| Question : | 
	 
	 
	 		| What is the measurement used in Selling Lumber ? | 
 
	  
	 	| Answer :
 | 
	  
	 		| Lumber is sold according to a special measure of volume called the board foot. | 
	 
	  
	 		| The number of board feet 
			= Thickness in inches x Width in feet x Length in feet | 
	  
	 		| For Example : | 
	  
	 		    | In case we want 
                  to calculate in board feet a Lumber that is 8 foot long 2 by 
                  4 then, 
 Number of board feet = 2 in x (4/12)ft x 8 ft = (64/12)ft = 5.3 board foot.
 
 2 inches is the thickness in inches, 
			(4/12) ft is the width in feet, 
			8 ft is the length in feet.

	 		| Here,  pricing is generally quoted per thousand board feet (MBF). |
