Quizplus · Accepted Answer

To calculate the board footage of a board, you multiply the length (in feet) by the width (in inches) by the thickness (in inches), and then divide by 12 to convert to board feet. 
For option A: (2 x 8 x 12)/12 = 16 board feet 
For option B: (4 x 4 x 10)/12 = 13.33 board feet 
For option C: (2 x 4 x 12)/12 = 8 board feet 
For option D: (2 x 6 x 10)/12 = 10 board feet

Therefore, the only option that contains 8 board feet is option C.
