Prepare Boards for Facing

What happens here

The presenter measures the vertical distance between the top of the uppermost fence board and the bottom of the lowest fence board, finding it to be approximately 43.75 inches. He decides to cut all face boards to 45 inches to create a 1-inch overhang at both the top and bottom. This overhang will allow water to drip off, preventing it from running down and rotting the wood underneath. He then stacks multiple fence boards on saw horses, ensuring they are flush on one end to prepare for cutting.

Goal: Determine the length and prepare face boards for cutting
