Once it's kiln dried, yellow pine is one of the lighter woods. I wouldn,t think a 4x12x10' should weigh much more than 60 lbs. Maybe not that much. Sorry, but the above answer is incorrect. Actually the weight of dried southern yellow pine is around 3 lbs per board foot. A 4x12x10' contains 40 board feet and therefore weighs approximately 120 lbs.

The above answer is conservative. The exact answer is yellow pine has a density of roughly 40lbs/ft^3. A 4x12 is actually 3.5"x11.25" = 39.38in^2.

Therefore for a 10ft section: (40lb/ft^3) x ((39.38in^2)/144) x (10') = 109.4 lbs.
