Activity

The picture shows the view of a levelling staff through a level's telescope. Give the three readings, upper stadia line, staff height and lower stadia line in metres to 3 decimal places, then calculate distance to staff using a stadia constant of 100. Stadia distances are only given to one decimal place to reflect the lack of precision with this method.

Only enter numbers - abbreviations such as 'm' will not be recognised.
