Irregular Volumes
Toggle between Average End Area and Cross-Section methods for irregular solids.
Use consistent units. Feet-based inputs return cubic feet and cubic yards.

Rows are sorted by station before calculating. Duplicate stations are skipped as errors.
Formula: Volume between stations = ((A1 + A2) / 2) × Δx
Great for the no-calculator PE items where only a few sections are given.
PE-style example (Average End Area)
Cross-section areas (sq ft) are given every 200 ft: 0, 320, 640, 410, 100. Loading the example pre-fills stations 0–800 ft and solves the total volume in cubic yards.
