answer question 40 only

Field measurements were taken along a proposed roadway alignment. The cross sections at the start of the project (21+70) and at the next three full stations (22+00, 23+00, 24+00) were examined. The cut areas and fill areas were calculated and are given in the following table. A 10% shrinkage is expected. The 1000 ft free haul area begins at station 23+60 and continues to station 33+60.

| Station | Cut area (ft²) | Fill area (ft²) |
|---------|---------------|----------------|
| 21+70 | 9 | 3 |
| 22+00 | 9 | 6 |
| 23+00 | 8 | 4 |
| 24+00 | 5 | 2 |
