I hope this is not old too...
A man decides the find out for himself whether or not "if you dig a hole straight down from America, you get to China". So he grabs his beautiful rosewood globe and drills a cylindrical tunnel diametrically through it, starting from America. He finds the other end is far from China... in fact it's in the southern hemispere.
So here's the question : If the length of the tunnel measured along its wall is 'L', what the volume of the material left in the globe after drilling out the tunnel ?
