You have 3 BCY of clay, after excavation you will have how many LCY?

Explanation:
Swell factor converts bank cubic yards to loose cubic yards. When soil is excavated, it loosens and expands, so the loose volume is larger than the in-place bank volume. For clay, a common swell factor is about 1.25. Multiply the bank volume by this factor: 3 BCY × 1.25 = 3.75 LCY. So after excavation you’ll have 3.75 LCY. The other numbers would imply different swell factors, which aren’t typical for this clay assumption.
