A cut list needs 12 boards at rough dimensions 1.25 inches thick, 8 inches wide and 6 feet long. Board feet = thickness(in) × width(in) × length(ft) ÷12. Purchase 15% extra volume for selection. Supplier price is $7 per board foot. Finished boards are 1 inches thick but all other dimensions remain the same. Ignore tax and further losses. Calculate the finished cut-list volume in board feet. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
