Question

a centimeter ruler is used to measure the length of the white object. please record the length from the image. the numbers represent centimeters with 9 smaller black lines between each centimeter. 6.00 cm 6 cm 6.3 cm 6.30 cm

Explanation:

Step1: Determine the scale of the ruler

The ruler has 9 smaller black lines between each centimeter. So, each small division represents \( \frac{1}{10}=0.1\) cm.

Step2: Identify the starting and ending points

Assume the starting point is at \(4.00\) cm (a major mark). The ending point is at the 23rd small - division after \(4.00\) cm. But if we consider the measurement from the correct alignment (assuming proper zero - point or starting - point consideration, and looking at the end of the object which is at the 23rd mark from \(4\) but in terms of reading: the object starts at \(4.00\) cm and ends at \(6.30\) cm. The ruler's precision allows us to read to the hundredth of a centimeter. Each centimeter is divided into 10 parts (since \(9 + 1\) intervals for each cm). So we can measure as \(6.30\) cm.

Answer:

\(6.30\) cm
