Pretty straightforward question! Don’t overcomplicate the answer.

  1. 1 Mile = 5280 Feet
  2. Assume each dash is 2’ x 10’ on a highway line, spaced by an interval of 30’
    a. Approximate paint thickness as 0.003 feet (roughly .2 millimeters)
  3. In each 40’ segment there’s one dashed line. 5280/40 = 132 dashes

Total Volume = 132 * (2’ * 10’ * 0.003’), which is 0.6 ft^3.
