Question

The most appropriate unit to measure the length of the book is

• A. Millimetre
• B. Metre
• C. Micrometre
• D. Centimetre

Answer 1

The correct option is D

Centimetre

1. We use smaller units such as millimetres and micrometres to measure the length of smaller objects so we do not use these units to measure the length of the book.
2. We do not prefer to use the unit metre to measure the length of the book as it is a big unit to measure it.
3. So, the most appropriate unit to measure the length of the book is a centimetre.

Hence, the correct answer is option D.
