Answer:
342yd^2
Step-by-step explanation:
The way I find surface area is by laying out the box and finding the area of each square seperately and then adding them together.
First, I placed the 7 on the wing to the side because that is the width.
Next, I placed the 13 on the long side of the big box because that is the length.
Then, I placed the 4 on the small side of the big box because that is the width.
After that I just did the multiplication for each box.
2(7•13) + 2(7•4) + 2(13•4) = 342
You can apply this same strategy to any surface area problem like this. The format will change based on the shape but that's pretty much it. Hope this helped

Let 
be the amount of parts the student answered correctly. Suppose that 
is a function between and the score of a student's project. As the student initially receives a fixed 
points for turning the project in and 
points for each correct part, the function is initially:
When the students receive
points for each correct part, the coefficient of changes, as the amount of points received per correct answer increases. Thus:
