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

Solve for x. 3x/2 = 15

defon

3x : 2 = 15

3x = 15 * 2

3x = 30

x = 30 : 3

x = 10

--------------------------------

3(10) :2 = 15
