In Table 73 the fractions are given in twelfths (small figures), 

 making adding easier. Thus the following 1-inch lumber would 

 be added: 



Size. Contents. 

 10' X 1"= 510 

 12' X 10"= 10 

 12' X 16"= 16 

 14' X 13"= 152 

 16' X 20"= 268 



Total=72f§ or 73| board feet. 



If it were 3-inch lumber the total would be multiplied by 3, or a 

 I jt total of 221 board feet.
