A classroom stair drawing has total rise 3220 mm and specifies 17 equal risers. There is one fewer tread than risers; each tread has going 280 mm. Ignore nosings and landings. Use these given drawing dimensions without assessing building-code compliance or structural suitability. Calculate the horizontal position after five goings in mm. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
