Answer 2

Screw gauge is the tool that could have been used to obtain these readings.

• A screw gauge is an apparatus that is used to measure lengths in the unit millimetre.
• In order to find the dimensions of the small book, it is placed between the gap in the screw gauge and the screw head is turned until the ratchet arrangement gives a click.
• The reading on the main scale is noted. The division on the circular scale coinciding with the reference line is read, multiplied by the least count and then, added to the reading on the main scale.
• This gives the measurement of the dimensions of the book.
