Problem Description:
The task involves measuring the length of each bar shown in the image using a ruler. The bars are marked on a ruler, and we need to determine their lengths accurately.
Solution Approach:
1.
Understand the Ruler Scale:
- The ruler is marked from 0 to 8 units.
- Each major division represents 1 unit.
- Minor divisions (if present) can help measure fractions of a unit, but in this case, the bars align with major divisions.
2.
Measure Each Bar:
- For each bar, identify the starting point (left end) and the ending point (right end).
- Subtract the starting point from the ending point to find the length of the bar.
3.
Record the Lengths:
- Write down the length for each bar in the provided answer section.
Step-by-Step Measurement:
#### 1. Bar 1:
- Starting point: 1
- Ending point: 5
- Length: \( 5 - 1 = 4 \)
#### 2. Bar 2:
- Starting point: 1
- Ending point: 6
- Length: \( 6 - 1 = 5 \)
#### 3. Bar 3:
- Starting point: 4
- Ending point: 7
- Length: \( 7 - 4 = 3 \)
#### 4. Bar 4:
- Starting point: 2
- Ending point: 4
- Length: \( 4 - 2 = 2 \)
#### 5. Bar 5:
- Starting point: 1
- Ending point: 7
- Length: \( 7 - 1 = 6 \)
#### 6. Bar 6:
- Starting point: 1
- Ending point: 4
- Length: \( 4 - 1 = 3 \)
#### 7. Bar 7:
- Starting point: 1
- Ending point: 4
- Length: \( 4 - 1 = 3 \)
#### 8. Bar 8:
- Starting point: 1
- Ending point: 8
- Length: \( 8 - 1 = 7 \)
#### 9. Bar 9:
- Starting point: 4
- Ending point: 7
- Length: \( 7 - 4 = 3 \)
#### 10. Bar 10:
- Starting point: 1
- Ending point: 8
- Length: \( 8 - 1 = 7 \)
Final Answer:
\[
\boxed{4, 5, 3, 2, 6, 3, 3, 7, 3, 7}
\]
Explanation:
Each bar's length is calculated by determining the difference between its starting and ending points on the ruler. The results are recorded in the order of the bars as presented in the image. This method ensures accuracy and consistency in measuring the lengths.
