I'm going to say that Link's boots are about a size 13, because that is what I have, and I am 6 feet tall. This means his boots length at the foot is thirteen and a half inches. And I will say that his boots stand at a foot high, and I'm going to add an extra inch for the unusually thick bottoms.
I'm using the volume of a rectangle to calculate the surface area of Link's boots from the height of the bottom of his foot to his ankle. And the volume of a cylinder for above his ankle to the top. So, this actually makes these boots solid, when they aren't.
Now then. A thirteen inch total height on these boots cuts into 4 inches from foot bottom to ankle. Plus an extra for the thickness. Width of my shoes at their widest on the bottom is almost 5 inches, so I'm just going to use 5.
Volume of a rectangle is base x width x height. This means it's volume is equal to 13 (base) x 5 (width) x 5 (height). A total of 325 in^3. I'm bad with math, so I forget what to do with it from here. I think I'm done with that though, so on to the cylinder that we will call Link's calf.
I'm going to use a diameter of 7 inches which I think is pretty decent sized for a calf muscle. Now, since we used 5 of the boot's height already, all we have now on it's height is 8 inches. The formula for the volume of a cylinder is Area x height. To find the area, we do pi x r^2. So, 3.5 ^2 = 12.25 x 3.14 = 38.465. Now, 38.465 x 8 inches for volume equals out at 307.72 in^3. Add the two together for the total volume and you get 632.72 in^3.
For the density of Iron, I'm using this source. http://www.coolmagnetman.com/magconda.htm
632.72 x 0.284 = 179.69248 pounds. So a little more than what average male humans weigh. I don't need to tell you to add in a reasonable weight for Link, do I? When you do that, you'll likely get something around 400 pounds. So let's find out what Dangoro's weight would be if he were human, but retained his size. Oh, and don't forget, I made those boots solid, as opposed to the normal hollowness they would normally be. And I'm pretty sure this is basic iron, which is probably heavier than what people would use in armors. I also made the bottom of the boots a perfect rectangle and a perfect cylinder, not what the boots are.
ScreamPaste suggested I use ballistics jelly for this, so I did.
Again based on the earlier image, I calculated Dangoro in a perfect sphere with a diameter of 14 feet, even though the picture says he would be 15. 14 feet is a total of 168 inches.
Wikipedia tells me the volume of a sphere is 4/3 x pi x r^3. So we know what the radius is, 7 feet. And we always know what pi is, good ole pi. Apple is my favorite. And the most American!
4/3 x 3.14 x 84(in.)^3 = 2,481,454.08in^3
Big number. So, density of ballistics jelly.
>_> I can't find it. If someone will provide me with that I'll finish this.
Also, anyone wanna check this crap? I am notoriously bad with anything in this area. I could have seriously ****ed up almost anywhere.
All this is to prove that the Iron Boots have to be heavier than Iron by the way.
