For all the computed values with decimals, use four (4) digits after the decimal. Differential leveling runs from BM10 to BM11 at a distance of 7.5 km. It was observed that the leveling rod was inclined 6° from the vertical every time the backsight is taken. The average BS reading is 3.15m and the average length per set-up is 300m. Determine the error every 300m set-up and the correct elevation of BM11 if the recorded elevation was 173.

Question
For all the computed values with decimals, use four (4) digits after the decimal.
Differential leveling runs from BM10 to BM11 at a distance of 7.5 km. It was observed that the leveling rod was inclined 6° from the vertical every time the backsight is taken. The average BS reading is 3.15m and the average length per set-up is 300m. Determine the error every 300m set-up and the correct elevation of BM11 if the recorded elevation was 173.20m.
