7.5 square feet
The boards are 2"x6"x 16 ft. Since each board is 0.5 ft wide and 16 ft long, it will cover 8 sq ft. 400/8 = 50, so you will need 50 boards.
A 2x12x12 foot board would not be measured in square feet but cubic feet and there would be 240 feet3

8 square feet.
A board foot is a unit of volume, while a square foot is a unit of area. The two units are therefore incompatible.

None. Board foot is a measure of volume not area.

It depends on the exposure. If you are lapping each board 1 1/4" you have a 6" exposure. This would give 6 square feet coverage per board, and would take 17 boards to cover 100 square eet (1 square) Exposure (in feet) * Length = Square foot of coverage per board 1 square = 100 square feet
