800 mm = 2.62 feet, approx.
Linear feet and feet means the same thing.
800 feet / 10 foot per board = 80 boards
50. Feet are always linear.
800 feet = 0.1515 miles
40 linear feet, or 40 feet = 12.192 metres.
It is a length of 520 feet.
14,500 linear feet is equal to about 2.746 miles.
As stated the question has no numerical answer. There are 200 linear fee of a 1 foot wide strip, 400 linear feet of a 6-inch wide strip, 800 linear feet of a 3-inch wide strip, etc. The formula is L = S x W where L=# of linear feet, S=#of square feet, and W=the reciprocal of the strip width in feet.
Linear feet are the same as feet, so the answer is 133 linear feet!
