The minimum size for a density test sample is 8 cubic inches. Which option matches?

Explanation:
The key idea is that a density test needs a specimen large enough to provide a reliable reading. Eight cubic inches is the smallest size that meets the standard, so it represents the minimum required volume. That’s why eight cubic inches is the correct match. A smaller sample, like six, wouldn’t meet the minimum and could give an inaccurate density due to insufficient material. Larger samples, such as ten or twelve cubic inches, do satisfy the requirement too, but they exceed the minimum rather than match it.
