This story was on page A11 of the Saturday, 5 February 2005, Arizona Republic."Police searching for marijuana in the Miami area discovered an entirely different stash buried four feet underground Friday: millions of nickels that vanished last year en route to the Federal Reserve in New Orleans."
The police found
3.6 million nickels. How many U.S. dollars is this? A nickel written as a decimal number is
3.6 millionnickels ended up weighing
450,000 pounds. How many ounces is this? There are
16 ouncesin a pound.
The stash of nickels were stored between
900bags. How many nickels per bag is this?
During a MAT102 lecture, we extended this BAB to calculate the weight per nickel. Our answer came out to be a completely bogus. The piece of data in question is that the nickels weighed
I used the web to find an archived copy of the news story and it said the nickels weighed almost
23 tons. [source::MSN.com]1) convert tons to pounds (lbs) assume 2,000 lbs. per 1 ton 23 tons approximates 23 x 2000 lbs (i.e. 46,000 lbs) 2) calculate lbs per nickel 46000 lbs 0.0127 lb --------------- = --------- 3600000 nickels 1 nickel 3) convert 0.0127 lb into ounces assume 16 ounces per pound 0.0127 x 16 = .2032 ounce 4) calculate how many nickels it would take to weigh 1 pound ? nickels 1 nickel --------- = --------- 1 lb 0.0127 lb 1 / 0.0127 = approximately 78.74 nickels ...or... ? nickels 1 nickel --------- = --------- 16 oz .2032 ounce 16 / .2032 = approximately 78.74 nickels [answer] It takes about 79 nickels to weigh one pound.
I decided to provide a hyperlink to this news story for future reference. Due to their archive policies, I was not able to hyperlink to the original story at AzCentral.com. I don't hyperlink to MSN.com; therefore, I found another copy of the story at FindArticles.com.
FindArticles.com:: Heist of a truck hauling 3.6 million nickels
Doh! FindArticles.com says the weight of the nickels was
22.5 tons. Recall, we used
23 tonsto figure out the weight of one nickel. MSN.com said the nickels weighed almost
22.5 tonsrounded up to the nearest whole ton is
23 tons; however,
The update provided by FindAricles.com indicates that the 3.6 million nickels weighed
22.5 tons. Recalculate the approximate weight of one nickel using
22.5 tonsinstead of
About the Original Error
In the original version of this BAB, I wrote that the
3.6 millionnickels weighed
450,000 pounds. This was mis-information (i.e. erroneous data), but I don't know how the error was introduced; in other words, either the Arizona Republic article was in error or else I made an error in reading or copying the data.
This BAB was created and presented during the Spring 2005 semester. It was presented during the Fall 2005 semester because of the GDT::BAB:: New Nickel Coming in 2006 that was created and presented during th Fall 2005 semester.
