Framing & StructuralQuestion 448 of 700
How many board feet are contained in 15 framing members that are each nominal 2x10 and 16 feet long? (Board feet per piece = nominal thickness in inches times nominal width in inches times length in feet, divided by 12.)
a.300 board feet
b.350 board feet
c.375 board feet
d.400 board feet
Explanation
Each piece = (2 x 10 x 16) / 12 = 320 / 12 = 26.67 board feet. Multiplied by 15 pieces = 400 board feet. The other choices result from dropping the piece count or mis-multiplying the thickness-width-length product.
