On a globe of the Earth, some rainy afternoon, find every point you can that's
exactly mid-way between the north and south poles, and mark each one with
a tiny pencil-dot.
When you've made enough dots, you'll begin to realize that they all line up
around the 'middle' of the Earth, crossing Africa, the Indian Ocean, the Atlantic
and Pacific Oceans, and the upper part of South America.
If you made millions and millions of these dots, each one exactly mid-way between
the poles, they'd blend together into a solid line, and that line is the Equator.
There are 3.7854 liters in one US gallon of anything.
Gallons and square miles can't be compared; a gallon is a measure of volume, whereas a square mile is a measure of area. But let's try to make sense of the apparently nonsense question. What if the question poster had asked, "How many gallons are there in a one-square-mile puddle of water that is a quarter of an inch deep?" That calculation is non-trivial and may yield an answer that is surprising. Here are some units and conversions that may be helpful: 1 square mile = 27878400 square feet 1 inch = 0.083333 foot 1 cubic foot = 1728 cubic inches 1 gallon = 231 cubic inches If you did the arithmetic right, that rather large puddle contains 4,344,685.7 gallons of water. (The proof is left to the reader.)

A composite number is an integer that is exactly divisible by at least one factor other than 1 and itself. There is an infinite number of composite numbers.
A prime number on the other hand can only be divided by 1 and itself. It's easy enough to infer that a composite number can be written as a product of prime factors:
2380 = 2 x 2 x 5 x 7 x 17
The first few composite numbers are:
Numbers which can be divided by other numbers besides 1. Numbers with factors besides 1 and themselves. Numbers which are not prime. 91 is composite because it is 13 x 7. But 41 is not composite because it is only 41 x 1. (of an integer) being the product of two or more factors greater than one; not prime.
