Question

The chain is about 10 centimetres long. Choose the option which is the best estimate for the length of the crayon.

• A. 8 centimetres
• B. 13 centimetres
• C. 5 centimetres
• D. 3 centimetres

Answer 1

The correct option is A 8 centimetres

The chain is a little longer than the crayon. Thus, 13 centimetres is a highly unreasonable estimate for the length of the crayon.

Also, the chain is not twice as long as the crayon. The crayon is just a little shorter than the chain. Thus, 8 centimetres seems like a more reasonable estimate for its length.
