Multiple Choice

The measurement of a cored specimen must be made using only a single measurement.

Explanation:
Cored specimens aren’t perfect cylinders, so relying on a single measurement can give a biased dimension due to ovality, taper, or beveled ends. To get a reliable size, you take several measurements of diameter in two perpendicular directions and average them, and you measure length at several points along the core and average as well. This helps account for irregularities and yields a more accurate volume for calculations like density and void content. Because of this, the statement is false—the measurement should involve more than one measurement.
