Follow-up to Math Rushmore: Crazy Horse, Crazy Math!

Friend of the blog, C. Wright dared (more or less) thegeometryteacher to explore a lesser known, but equally fascinating monument in the Black Hills of South Dakota (in the United States, for you international readers).

A bit of background: Crazy Horse was a warrior from the Lakota tribe that resided in the American Great Plains. Construction of this gigantic monument started in the 1940’s and remains incomplete. It is truly a fascinating story. The story of Crazy Horse is equally fascinating, by the way, especially his connection to General Custer (who was raised in Michigan) and The Battle of The Little Big Horn in 1876.

Here are some photos of the monument.

 

And a profile shot.

C. Wright’s comment “What math could thegeometryteacher do with this monument?” raises some interesting possibilities. And me, being more of a question-asker than answerer thought of a possibility:

Could Teddy Roosevelt’s Glasses (in Mount Rushmore) fit Crazy Horse (in his monument?)

So, let’s go with that one. Think about what information you would need in order to answer that question. What would the plan be once you had that information?

There may be a video solution in the mix for this problem. Don’t wait for it, though.

Math Rushmore

I am fascinated by Mount Rushmore. First of all, the fact that during the great depression, funding and technology allowed for 60-foot likenesses to be carved into a granite mountain face is incredible to me. Apparently, I am not the only one. According to the Wikipedia site for Mount Rushmore, over 2 million people visit Mount Rushmore each year.

But, let’s turn our fascination to the incredible opportunities that we have with these carvings to look at. What kind of math can we do with four gigantic granite carvings of four dead presidents? (Washington, Jefferson, Lincoln, T. Roosevelt)

I suspect a lot.

First question that sticks out in my mind: What would the Mount Rushmore George Washington’s hat size be?

How tall would Abe Lincoln be if his face where really that big? Or how tall would his signature top hat be?

Jefferson is on the American nickel, right? How big would a nickel be to fit the Mount Rushmore Jefferson head on it? How much would that nickel be worth? Certainly more than 5 cents.

Or what if Roosevelt sneezed? Just askin’…

Can you think of any other questions? Or can you answer any of my curiosities?
