How many kilometers wide is something 80 feet wide?
80 feet = 0.024384 kilometers.
What is the size in square miles of the Universe?
First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known. The observable Universe has a radius of about 46 billion light-years. Convert that to kilometers or miles if you like. One light-year is about 10 million million kilometers. But the entire Universe is probably much, much bigger.First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known.

What does power of 10 to 10 to the power of 100 mean in math?
it is the total (estimated) area of the universe, measured in either kilometers or meters
Would a googolplex people fit in the universe?
A googolplex people could definitely fit in the universe. Googolplex, while a very large number, is also finite. There is a good chance the universe is infinite, depending on which model you follow. The observable universe (the part with light in it), however, is about 93 billion light years wide. If we assume that the average human is about a foot wide (from chest to back, not shoulder to shoulder), and six feet tall, then 4.01 * 1081 humans could fit in the universe. This is no where near googolplex, so your answer would differ depending on your definition of the universe. Note: my calculations involved assuming humans were about a 1*1*6 prism, and could be stacked right next to each other. Additionally, my estimation of the area of the universe is much larger than it actually is because it isn't a perfect cube, like I used in these calculations. However, because the number was so far short of googolplex, this estimation will do. For those of you who do not know what googolplex is, it is one followed by a googol zeros. Googol is one followed by a hundred zeros. So googleplex is 1010000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
What is the time-line of the discovery of the universe?
The universe is older than mankind and mankind evolved within the universe. So the universe could not be discovered.
