The number of rungs is eleven. Measured from the bottom rung up, their vertical distances are 0, 0.25, 0.50, 0.75, 1.0. 1.25, 1.50, 1.75, 2.00, 2.25 and 2.50 meters. Rung length increases from 45 at the bottom to 25 at the top, so rung lengths are:
45, 43, 41, 39, 37, 35, 33, 31, 29, 27 and 25 cm.
Add up those numbers for wood length required. Looks like 11 x 35 = 385 cm
