Square feet measure area and linear feet measure length. If a board is one (linear) foot long, that does not tell you how much area it covers, unless you also know the width.
96 square feet
10.5 feet x 6 feet = 63 square feet.
7.5 square feet
48 square feet.
110 square feet.
Depends on the size of the board.
A 2x12x12 foot board would not be measured in square feet but cubic feet and there would be 240 feet3
None. Board foot is a measure of volume not area.

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.
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
