How tall would a stack of 1 Million Pennies Be?
Each penny is about 1.52 mm thick. A stack of 1 million pennies would be:
\[ 1,000,000 \times 1.52 \text{ mm} = 1,520,000 \text{ mm} \]
Convert to meters:
\[ 1,520,000 \text{ mm} = 1,520 \text{ meters} \]
So, the stack would be approximately 1,520 meters tall, or 1.52 kilometers.
