# Step 1: Interpreting and Adjusting the Table
Given the instructions:
- **At Station 1100:** The end-area cut is modified (details not specified, so assume the value remains).
- **At Station 1800:** The end-area fill is modified (similarly, keep the provided value).
- **Cubic yards (ccy) to bank cubic yards (bcy):** Use \( \text{bcy} = \frac{\text{ccy}}{0.9} \).
We will focus on **Station 1100 (cut)** and **Station 1800 (fill)** for these modifications.
## Original Table (with assumed/placeholder values)
| Station | End-area Cut (sf) | End-area Fill (sf) | Volume of Cut (bcy) | Volume of Fill (ccy) | Strip Cut (bcy) | Strip Fill (bcy) | Mass Ordinate |
|---------|-------------------|--------------------|---------------------|----------------------|-----------------|------------------|---------------|
| 1000 | 0 | 0 | - | - | - | - | 0 |
| 1100 | 400 | 0 | *Modified* | - | - | - | ? |
| 1200 | 523 | 0 | - | - | - | - | ? |
| 1300 | 410 | 0 | - | - | - | - | ? |
| 1400 | 368 | 0 | - | - | - | - | ? |
| 1500 | 233 | 62 | - | - | - | - | ? |
| 1600 | 136 | 237 | - | - | - | - | ? |
| 1700 | 85 | 569 | - | - | - | - | ? |
| 1800 | 72 | 591 | - | *Modified* | - | - | ? |
| 1900 | 0 | 219 | - | - | - | - | ? |
| 2000 | 0 | 257 | - | - | - | - | ? |
| 2100 | 0 | 69 | - | - | - | - | ? |
| 2200 | 0 | 0 | - | - | - | - | ? |
### Image Example
_Example of end-area method (not specific to this table, for visual context):_
*Image: Cross-section showing end-area method for volume calculation*
## Modifications
1. **End-area cut at Station 1100:**
- If the volume of cut at Station 1100 was previously in ccy, convert to bcy:
\[
\text{Volume of Cut (bcy)} = \frac{\text{Volume of Cut (ccy)}}{0.9}
\]
2. **End-area fill at Station 1800:**
- If the volume of fill at Station 1800 was in ccy, convert to bcy:
\[
\text{Volume of Fill (bcy)} = \frac{\text{Volume of Fill (ccy)}}{0.9}
\]
## Adjusted Table (focusing on 1100 & 1800)
Suppose the cut at 1100 and fill at 1800 were given as 900 ccy and 1350 ccy, respectively, as an example.
| Station | End-area Cut (sf) | End-area Fill (sf) | Volume of Cut (ccy) | Volume of Cut (bcy) | Volume of Fill (ccy) | Volume of Fill (bcy) |
|---------|-------------------|--------------------|---------------------|---------------------|----------------------|----------------------|
| 1100 | 400 | 0 | 900 | 1000 | - | - |
| 1800 | 72 | 591 | - | - | 1350 | 1500 |
- **Conversion shown:**
- \( 900 \div 0.9 = 1000 \) bcy at 1100 (cut)
- \( 1350 \div 0.9 = 1500 \) bcy at 1800 (fill)
## Summary
- Adjusted the values for cut (1100) and fill (1800) using the conversion factor.
- Focused on those stations as per your instructions.
- All other values remain as in the original data unless further modifications are specified.
If you have the actual ccy values for cut and fill at the specified stations, substitute them into the formulas above.
