This question can be solved without any engineering intuition…

Pretty straightforward question! Don’t overcomplicate the answer.

- 1 Mile = 5280 Feet
- 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) - 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.
