Taconite pellets have a bulk density of approximately 129 pounds per cubic foot (this takes into account spaces in between individual pellets, hence the term bulk density). To figure out the volume of 60,000,000 tons, we multiply that amount by 2240 (pounds in a long ton) to get weight in pounds - this turns out to be 134,400,000,000 (that's 134.4 billion) pounds. Divide this by the density above to get a volume of 1,041,860,465 (that's 1.04 billion) cubic feet. Take the cube root of this to get the length of a cube that would equal this volume - this turns out to be 1014 feet. Imagine a cube of taconite that is that long and wide, and extends that high into the sky!
