1. What is the total board footage for a 4/4 board that is 6 inches wide and 12 feet long?
A) 4 bd. ft.
B) 6 bd. ft.
C) 8 bd. ft.
D) 12 bd. ft.
, Page 2 of 132
Answer: B
Rationale: Board footage = (Thickness in inches × Width in inches × Length in feet) ÷ 12. For 4/4 = 1 inch
thick: (1 × 6 × 12) ÷ 12 = 6 board feet.

prevent board chatter?
A) Infeed roll

cabinet door?
A) Dovetail joint
B) Mortise-and-tenon joint
