James ordered a fishing rod, priced at $3.56. Unfortunately, James is an Eskimo who lives in a very remote part of Greenland and the import rules there forbid any package longer than 4 feet to be imported. The fishing rod was 4 feet and 1 inch, just a little too long, so how can the fishing rod be mailed to James without breaking the rules? Ideally James would like the fishing rod to arrive in one piece!
Insert the fishing rod into a box which measures 4 feet on all sides, the fishing rod will fit within the diagonal of the box with room to spare.
Presume that you do not know what a rhino looks like. Now the question goes like this:
If one day while walking in a forest with two of your close friends, one friend shows you an elephant and tells that this is a rhino, and another friend shows you a hippopotamus and tells you that this is rhino, who would you believe and why?
I told you that you do not know what a rhino looks like, not that you are unaware of what a hippo and elephant look like. So you shouldn't believe either of them.
How much dirt would be in a hole 6 feet deep and 6 feet wide that has been dug with a square edged shovel?
None.
No matter how big a hole is, it's still a hole: the absence of dirt.
And those of you who said 36 cubic feet are wrong for another reason, too.
You would have needed the length measurement too.
So you don't even know how much air is in the hole.
