Let's work through the problem step by step.

### Given:
- Thickness of one penny: 1.55 millimeters
- Total value of pennies: $231
- 1 penny is worth $0.01

### Steps:
1. **Find the number of pennies:**
   \[
   \frac{231}{0.01} = 23100 \text{ pennies}
   \]

2. **Calculate the height of the stack in millimeters:**
   Each penny is 1.55 mm thick, so the total thickness of 23,100 pennies is:
   \[
   23100 \times 1.55 = 35805 \text{ mm}
   \]

3. **Convert millimeters to meters:**
   Since 1 meter = 1000 millimeters, divide by 1000:
   \[
   \frac{35805}{1000} = 35.805 \text{ meters}
   \]

### Final Answer:
The stack would be **35.805 meters** tall.

Here are 5 follow-up questions to deepen your understanding:
1. How would the height of the stack change if pennies were 2 mm thick instead?
2. What would happen to the total height if you stacked $462 worth of pennies instead?
3. How would the answer change if the thickness of the penny was given in inches instead of millimeters?
4. Can you convert the total height into centimeters instead of meters?
5. How would you approach this problem if asked to find the height in feet instead of meters?

**Tip:** Always remember to check units when solving measurement conversion problems to avoid errors!

A penny is 1.55 millimeters thick. If you stacked $231 worth of pennies on top of each other, how tall would the stack be, in meters?
