300 Hurdles means 300 meter hurdles. 300 meters is equivalent to 328.084 yards. Women's hurdles are 30 inches tall (Men's are 36").

Because the hurdles for men are set at different distances from the starting line than for women. For example: The mens hurdles start at the blue line, so the womens would start about 2 inches away at the yellow line. Additionally, elite men's stride length would not allow them to hurdle at the distance that womens hurdles are set at; it's simply too short.

The distance is 110m rather than 100m because they wanted men to be able to run it whilst fitting 3 steps in-between the hurdles without changing the number of hurdles in the race from 10. 10 hurdles in the race is consistent with all the hurdle events, so they increased the distance to make the men's race more fluid, as mens' strides are typically longer than womens'.

In the 400 meter hurdle, there are 10 hurdles. Each hurdle is 30" tall with 35m between them. There is a 45m distance before the first hurdle and a 40m distance to the finish line from the last hurdle.
The distance between 300 Hurdles (or 400 Hurdles) is 35 meters. The distance to the first hurdle (in high school races) is 45 meters and 10 meters from the last (8th) hurdle to the finish line. This is exactly the same as the first 300 meters of a 400 Hurdle race, though the relative position on the track is moved to finish at the common finish line.
