We want to find the surface area of this prism, which is going to be a tent.
00:05
So what i noticed is we have the front and the back are both triangles.
00:09
So let's start with those.
00:11
We see then that the base of this triangle is 2, and the height is 1 .7.
00:20
So that means the area is going to be 1 half base times height, which is going to be 1 half of 2 times 1 .7.
00:29
But we have two of those.
00:30
So therefore, to make sure i have two of those, i'm going to multiply by two.
00:35
And that's going to leave me my area to be two times 1 .7 or 3 .4.
00:41
So that's going to be my triangles in the front and the back.
00:45
Now, i notice the two sides are rectangles...
