Final answer:
The height of a stack of 2.5 x 10^9 pennies, each with a thickness of 5.98 x 10^-2 inch, would be calculated as 2.5 x 10^9 times 5.98 x 10^-2, resulting in 1.495 x 10^8 inches tall.
Step-by-step explanation:
The question asks us to calculate the height of a stack of pennies. Given that the thickness of a U.S. penny is 5.98 × 10-2 inch, and there are 2.5 × 109 pennies in the stack, we find the height by multiplying the number of pennies by the thickness of one penny.
To calculate the height:
- Multiply the number of pennies (2.5 × 109 pennies) by the thickness of one penny (5.98 × 10-2 inch).
- The height of the stack is 2.5 × 109 × 5.98 × 10-2, or 1.495 × 108 inches.
This gives us the total height of the stack of pennies.
