Physical quantities and measurement techniques — practice question

A manufacturer checks the three dimensions of a wooden floor tile with three separate instruments. The tile’s approximate measurements are shown as: length $0.4\,\text{m}$, width $0.08\,\text{m}$ and thickness $0.005\,\text{m}$. Which instruments are used to measure each of these dimensions accurately?

  • Alength: metre rule; thickness: micrometer; width: calipers
  • Blength: metre rule; thickness: calipers; width: micrometer
  • Clength: micrometer; thickness: metre rule; width: calipers
  • Dlength: calipers; thickness: micrometer; width: metre rule
