2. Several lines of levels were run over different routes from BM1 in order to set BM2 and establish its elevation. The lengths of these routes and the value of the elevations determined are shown blow. Determine the most probable elevation of BM2. Show your final answer and your computations in the table. Any additional work may be shown below the table. Route a C d Length (miles) 4 8 2 6 Measured Elevation (ft) 973.09 973.56 973.24 973.70

Line levels between BM1 and BM2 are run over four different routes. The elevation of BM1 is 640.00 m. The lengths of line and observed differences in elevations are shown in the tables. Determine the least square estimate of elevation of BM2. BM2 is higher than BM1. a. 640.69 b. 641.28 c. 640.39 d. 641.21

QUESTION 10 A cutting is to be formed on a straight section of a proposed road. The values of eight consecutive cross sectional areas taken at a constant horizontal distance interval of 20m are 325m², 398m², 456m², 580m², 634m², 546m², 447m² and 362m² respectively. Calculate the volume contained between the first and last cross section using : a. End areas method b. Prismoidal formula
