If the length of each paper clip is 1 inch, what is the estimated length of the toothbrush?

• A. 4 inches
• B. 5 inches
• C. 8 inches
• D. 6 inches

Answer 1

The correct option is D 6 inches

$\text{Say:}$
The length of each paper clip = 1 inch

$\text{Steps:}$
$\bullet$ Around 2 more paper clips can be used along with the 4 paper clips already placed to measure the length of the toothbrush.

$\bullet$ As the length of each paper clip is 1 inch, the length of 4 + 2 = 6 paper clips will be 6 inches.

$\bullet$ So, the estimated length of the toothbrush will be around 6 inches.

$\bullet$ Hence, option C is the answer.

$\text{Probing Question:}$How many paper clips will be used if the length of each paper clip is 2 inches?
A: Around 3 paper clips will be used to estimate the length of the toothbrush if the length of each paper clip is 2 inches.
