Depends on the size of the board.
(12) x (8.25/12) = 8.25 square feet
No they are differant units of measurement. Board feet, is actually a measurement of volume. 1 board foot is the volume of a board 12" wide by 1" thick by 1 foot long. So to calculate board foot you would also need to know the thickness. Whereas linear feet is a measurement of length, equal to 12 inches, in this case. You can also have linear inches, yards, furlongs, etc.
That depends on how wide your board is. A six inch wide board will need 25 x 25 x 2 (1250) linear feet to cover the area. A three inch wide board will need 25 x 25 x 4 (2500) linear feet to cover the area.
The big board would suit your feet unless your feet are huge there is no need to take the size of your board to any extreams. but if your shoe size is like a mens size 10 to like a 14 dert dah der thick wide big board would suit you.
you will need the board's thickness to answer this question.
You need to know the Chipset of your board
To determine how many 1x6x16 boards you need to cover 740 square feet, first calculate the coverage of one board. A 1x6 board is 6 inches wide, which is 0.5 feet, and 16 feet long. The area of one board is 0.5 feet x 16 feet = 8 square feet. Therefore, to cover 740 square feet, you would need 740 ÷ 8 = 92.5 boards. Since you can't purchase half a board, you would need to round up to 93 boards.
1,200 board feet.
cubic feet x 12 = board feet
No. You only need wax on the top of a surfboard to help keep your feet on the board.
