Answer:
400000 pennies
Step-by-step explanation:
A penny is about 5×10^-3 feet thick. The One World Trade Center building is about 2,000 feet tall.
The number of pennies that would be in a stack of pennies as tall as the One World Trade Center building is calculated as:
Height of the building ÷ Thickness of a penny
Height of the building = 2000 feet
Thickness of a penny = 5 × 10^-3 feet
Hence:
= 2000feet/ 5 × 10^-3 feet
= 400000 pennies
