Steps of doom!

An individual step is 180mm high (rising) and 240mm (going) deep. In total, there are 35 of these to the production office, split over five flights (including the two steps right at the bottom). There are five landings between the first step and the production office door, averaging approximately one meter. Therefore the total horizontal distance travelled in mm is 240x35+(5x1000)=13400, or 13.4 metres, and the total vertical distance is 180x35=6300, or 6.3 metres. Making these dimensions into the short sides of a triangle, it would seem that the total rough distance travelled by someone going up Veloce stairs is the square root of(13.4x13.4) + (6.3x6.3). Which is about 14.8 metres, at an average gradient of 25 degrees. They have black hard rubber noses, covering theleading 75mm of the top surface of each step, with five horizontaltreads running the length of each one at a depth of 1mm. Each nose formsa smooth rounded overhang that juts out 30mm and has a depth of 30mm. None of the steps are loose

Don't ask me how I know this, I have a good memory... Sounds like a lot of climbing, or arse shuffling...
