Which should be used to measure the length of a bookcase? a. thermometer b. tape measure c. clock d. scale

Okay. A thermometer measures temperature, a clock measures time and a scale measures weight. We are looking for the length of the bookcase, so we would use a tape measure. A tape measure measures length. The answer is B.

Hey there!

The correct answer to your question is option B.

If you wanted to measure the length of a bookcase, you would want to use a tape measure. A thermometer is used to check the temperature of something, a scale is used to check the weight of something, and a clock checks the time.
A scale, clock, and thermometer will not measure length.

Hope this helps you.
Have a great day!
