Answer

To find 34% of 12 km, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Percentage**:
- 34% means 34 out of 100.
- To find 34% of a number, we can multiply that number by 34 and then divide by 100.

2. **Convert Kilometers to Meters**:
- Since 1 km = 1000 m, we need to convert 12 km into meters.
- Calculation:
\[ 12 \text{ km} = 12 \times 1000 \text{ m} = 12000 \text{ m} \]

3. **Calculate 34% of 12000 m**:
- Now we will calculate 34% of 12000 m.
- Calculation:
\[ 34\% \text{ of } 12000 \text{ m} = \frac{34}{100} \times 12000 \]
- Simplifying this:
\[ = 34 \times 120 = 4080 \text{ m} \]

4. **Convert Meters to Centimeters**:
- Since the final answer is required in centimeters and 1 m = 100 cm, we convert 4080 m into centimeters.
- Calculation:
\[ 4080 \text{ m} = 4080 \times 100 \text{ cm} = 408000 \text{ cm} \]

5. **Final Answer**:
- Therefore, 34% of 12 km is 408000 cm.
