You have 2 BCY of sand, after compaction you will have?

Explanation:
When you compact soil, its volume decreases while the mass stays the same because the particles pack more tightly. Start with 2 bank cubic yards of sand; after compaction, the volume is slightly less, typically about 98% of the loose volume for sand. Multiply 2 by 0.98 to get 1.96, so the compacted volume is 1.96 cubic yards (1.96 CCY). That matches the given answer because compaction doesn’t increase volume and a small shrinkage is expected with sand. Options that increase volume aren’t possible from compaction, and one option implies a much larger shrinkage than is typical for sand.
