Framing & StructuralCâu 388 / 700
How many board feet are contained in ten framing members that are each 2 inches thick, 6 inches wide, and 12 feet long?
a.60 board feet
b.100 board feet
c.120 board feet
d.144 board feet
Giải thích
Board feet per piece equals (thickness in inches x width in inches x length in feet) divided by 12: (2 x 6 x 12) / 12 = 12 board feet each. Ten pieces total 120 board feet. 60 is the count for five pieces; 100 and 144 do not match the calculation.
