The answer is essentially this: the Empire State Building is approximately 100 storeys tall [it is 102 precisely]. That's at least 100 times the height of a typical room measured from the inside. I'd have to divide the skyscraper-high pennies column into around 100 floor-to-ceiling-high columns. That would be quite a challenge for your average apartment building!
Instead, imagine putting all the coins in one big pile. That's what makes the penny tower so unstable - there are just too many small objects in the way preventing it from being taller. The pile of pennies will inevitably collapse under its own weight.
Here's another example: try and build a tower out of toothpicks. It's impossible! You can stick to my first example and build a tower of pennies (or any other coin) instead.
Consider how many stacked pennies equal one inch to do this. Let's pretend it's 15. Then, knowing that there are 12 inches in a foot and that the Empire State Building's height is 1500 feet, you multiply to reach an approximate result of 270,000 pennies, which equals the height of the Empire State Building. This method is accurate to within about 3%.
The value of $1 in 1916 was equivalent to the value of $1 in 1996: $20 (100 cents) so a stack of coins worth $20 (or more) would be 1 foot high. Today, the value of a dollar is approximately $30 so a stack of coins now would be about 1-1/4 feet high.
In fact, a stack of coins today would weight about 50 pounds! That's over 20 times as much coin as was used back then!
The answer isn't quite as simple as multiplying $20 by 20 because there are various sizes of coins available in modern stacks.
This means that one must have access to about 270,000 pennies to reach the height of the Empire State Building.
The average American coin has a diameter of 1.5 inches. There are 257 coins per dollar value. Thus, it takes about 25,700 dollars' worth of coins to reach the height of the Empire State Building.
In real life, it would take much more than 25,700 dollars to reach the height of the building because you would need to purchase lots of other things too, such as food and clothes. The estimate does not include any savings for reinvesting money or assuming any debt. Also, the building is not perfect so some higher amounts of money may be needed but most people would agree that $25,700 is a very good estimate.
In conclusion, one needs a lot of money to reach the height of the Empire State Building.
270,000 cents Then, knowing that there are 12 inches in a foot and that the Empire State Building's height is 1500 feet, you multiply to reach an approximate result of 270,000 pennies, which equals the height of the Empire State Building. This calculation assumes that 1 cent is equal to 1 penny.
