An infinite set is exactly what its name suggests: <em>a set with an infinite number of elements</em>.

One example that you'll no doubt be familiar with is the set of natural numbers, N. Also called the "counting numbers," the natural numbers are the positive whole numbers 1, 2, 3, etc. Since there is no "last" natural number, N is considered an infinite set. More specifically, it's what's called <em>countably infinite</em>. More on that in a bit.

Another example of an infinite set is the set of real numbers, R, which includes all of the naturals, integers, rationals, and irrationals. R is also an infinite set, but it turns out, shockingly, that it's <em>a bigger kind of infinity; </em><em>uncountably infinite</em>, to be precise. We say that a set is <em>countably infinite </em>if every element can be matched up with a natural number - in other words, if there's a way the elements can be lined up and counted one after another in some way. This is true of the integers and rational numbers (and I've attached one way you can "count" the rational numbers in order), but <em>not </em>the irrationals.

Im not sure how to find the surface area. 35 points
Serga [27]

Answer: 3060 ft^2

Step-by-step explanation:

We will calculate the surface area of the rectangular prism and the triangular prism separately and then subtract off the face that isn't on the surface.

For the rectangular prism:

SA= Ph + 2B

P = 36+36+10+10

P = 92

B = 36*10 = 360

SA = 92*20+2*360

SA = 1840+720

SA = 2560

We subtract off the face on the right of the rectangular prism because it isn't on the surface so we get 2560-200 = 2360

Now for the triangular prism:

SA= Ph + 2B

P = 15+20+25

P = 60

B = 15*20/2

B = 150

SA = 60*10+2*150

SA = 600+300

SA = 900

Again we subtract off the face on the left bescause it's not on the surface so we get 900-200 = 700

Therefore, the total surface area = 2360+700 = 3060 ft^2
