To solve the problem of determining the length of each bar above the ruler, we need to carefully read the metric ruler for each bar. Here's a step-by-step explanation of how to do this:
Steps to Read a Metric Ruler:
1.
Identify the Starting Point: Note where the left end of the bar aligns with the ruler.
2.
Identify the Ending Point: Note where the right end of the bar aligns with the ruler.
3.
Calculate the Length: Subtract the starting point from the ending point.
Solution for Each Bar:
####
Bar 1:
-
Starting Point: 3 cm
-
Ending Point: 8 cm
-
Length: \( 8 - 3 = 5 \) cm
####
Bar 2:
-
Starting Point: 18 cm
-
Ending Point: 24 cm
-
Length: \( 24 - 18 = 6 \) cm
####
Bar 3:
-
Starting Point: 14 cm
-
Ending Point: 20 cm
-
Length: \( 20 - 14 = 6 \) cm
####
Bar 4:
-
Starting Point: 22 cm
-
Ending Point: 29 cm
-
Length: \( 29 - 22 = 7 \) cm
####
Bar 5:
-
Starting Point: 25 cm
-
Ending Point: 32 cm
-
Length: \( 32 - 25 = 7 \) cm
####
Bar 6:
-
Starting Point: 29 cm
-
Ending Point: 36 cm
-
Length: \( 36 - 29 = 7 \) cm
####
Bar 7:
-
Starting Point: 60 cm
-
Ending Point: 67 cm
-
Length: \( 67 - 60 = 7 \) cm
####
Bar 8:
-
Starting Point: 3 cm
-
Ending Point: 8 cm
-
Length: \( 8 - 3 = 5 \) cm
####
Bar 9:
-
Starting Point: 35 cm
-
Ending Point: 42 cm
-
Length: \( 42 - 35 = 7 \) cm
Final Answers:
1. \( 5 \) cm
2. \( 6 \) cm
3. \( 6 \) cm
4. \( 7 \) cm
5. \( 7 \) cm
6. \( 7 \) cm
7. \( 7 \) cm
8. \( 5 \) cm
9. \( 7 \) cm
Boxed Answer:
\[
\boxed{5, 6, 6, 7, 7, 7, 7, 5, 7}
\]
