Explanation / Answer

(1) Point B1 has lower elevation than finish, so it is fill, = 179=178.5 = 0.5'

(2) Point B2 has higher elevation than finish, so it is a cut = 179-179.2 = -0.2'

(3) Average elevation of the area = (177.0 +178.0 + 178.5 + 180 + 178.3 + 178.5 +179 + 180.2 + 178.8 + 179.2 + 180.1)/11 = 1967.6/11 = 178.872'

178.872' is lower than finish elevation of 179', so a fill of 179 - 178.872 = 0.128' thickness has to be

Total area = 20*30 - 10*10 = 500 square units.

So Fill Volume = Vc = 500*0.128 = 64 cubic feet, has to be borrowed/Imported.
