OUTDOOR MATERIALS / DECKING
Estimate whole stock deck boards from deck area, board width, installation gap, board length, and cutting allowance.
Use boundary
Deck area is divided by the board-plus-gap module to derive total length, then allowance and whole stock rounding apply.
Total board length = deck area / (board width + gap) x (1 + waste); boards = ceiling(length / stock length).
