Depends on the wood. Here is a link to a web site with specific weights for different materials (http://www.reade.com/Particle_Briefings/spec_gra2.htm)l
If you by 2x4x10 mean 2 inch x 4 inch x 10 feet that would be 960 cubic inches. 1 cubic feet is 12 inch x 12 inch x 12 inch = 1728 cubic inch
So 960 cubic inch is 0.555 cubic feet
Ex
From web site: Aspen wood= 26 lb/cubic foot
26 lb x0.555 = 14.43 lb
If you mean 2 * 4 * 10 cm that makes 80 cm3 which would weigh in the following woods (density in parentheses):
Balsa (0,12 - 0.38): 10g - 30g
Maple (0.60) 48g
Ebony (1.25) 100g
Aspen (0.40) 32g
Oak (0.8) 64 g
Pine (0.35 - 0,67) 28 g - 54 g
The densities above are for dry wood (12% humidity by weight)
