Question

Measure the width of a standard sized piece of paper (printer paper works great) in centimeters. Choose the answer that best represents the correct number of significant figures allowed by the ruler and is closest to your measured value.Group of answer choices21.6 cm215.9 cm21.59 cm

Answer 1

The total length of a ruler is around 30 cm, then you can't measure something larger than 30 cm, then we cannot measure 215.9 cm with the ruler. You can't measure lengths with more than one decimal place, then we cannot measure 21.59 cm with a ruler.

Then the correct answer is 215.9 cm
