Show the working

1. Available clear width = 144 − (9 × 2.5) = 121.5 in.
2. Equal clear gap = 121.5 ÷ 8 = 15.188 in.
3. Material length = 9 × 4 ft + 2 × 12 ft = 60 ft.
4. Apply 10% allowance and divide by 8 ft stock = 9 pieces.

Layout marks assume one straight uninterrupted span with the first batten at the left edge and the last batten at the right edge. Re-measure real walls and resolve corners/openings before cutting.
