We are asked to estimate how high in miles you can stack up an entire avogadro's number of oranges covering the entire earth.
00:56
Okay, well, this sounds like a fun question.
01:00
So we're going to figure out, just looked it up, and an orange, i should actually pick something sort of orangy.
01:10
And orange is about two and a half inches in diameter.
01:31
The earth is about 196 .9 times 10 to the 6 miles squared, 1 .96 times 10, 1 .969, 196 .9, times 10 to the 6 miles squared is 1 .96 .9 times 10 to 6 miles squared is 1, 196 .9 times 10 to 6 miles 5 ,280 feet.
02:23
I've got to square that times one foot is 12 inches.
02:32
This will equal 190, clear, clear.
02:36
196 .9 times 10 to the 6th times 5280x squared times 12x squared.
02:48
Enter.
02:49
And i get 7 .90 times 10.
02:56
To the 17th square inches.
03:01
Okay.
03:05
So let's see.
03:15
One orange is 2 .5 inches.
03:27
It will cover a square.
03:35
What's 2 .5? so if i were to pile these up, hmm, they keep getting bigger each time i added a layer on...
