Let’s go step by step to measure each green bar using the metric ruler shown.
Each ruler is marked in centimeters (cm), and each small line between the numbers represents 1 millimeter (mm). But since we’re measuring to the nearest whole centimeter (as the answer lines are blank and no decimals are asked for), we’ll look at where the end of each green bar lines up with the closest whole number on the ruler.
We start from the left edge of the ruler — that’s always 0 cm. The green bar starts at 0, so we just read where it ends.
---
Bar ①: Ends right at the 3 cm mark →
3 cm
Bar ②: Ends at the 8 cm mark →
8 cm
Bar ③: Ends at the 2 cm mark →
2 cm
Bar ④: Ends at the 9 cm mark →
9 cm
Bar ⑤: Ends at the 6 cm mark →
6 cm
Bar ⑥: Ends at the 10 cm mark →
10 cm
Bar ⑦: Ends at the 5 cm mark →
5 cm
Bar ⑧: Ends at the 3 cm mark →
3 cm

All measurements are straightforward because each bar ends exactly on a whole centimeter mark. No need to estimate or use millimeters here.
Final Answer:
① 3
② 8
③ 2
④ 9
⑤ 6
⑥ 10
⑦ 5
⑧ 3
