Step-by-step explanation:
<em>Hey there!</em>

Well to find SA we need to find the area of the rectangles.
So lets do the top rectangle,
6*6 = <u>36</u>
Now lets do the the left rectangle,
10*6 = <u>60</u>
Now lets do the far right one,
6*4 = <u>24</u>
Now lets do the second highest rectangle,
4*6 = <u>24</u>
Now lets do the rectangle facing the right side,
6*6 = <u>36</u>
Now we can do the bottom rectangle,
6*10 = <u>60</u>
Now lets do the 2 facing front and back,
6*10 = 60
4*4 = 16
60+16 = 76
76*2 = <u>152</u>
Now we can add everything,
152 + 60 + 36 + 24 + 24 + 60 + 36
= 392 in^2

Ok? So? What is the question here?
