Lets find the area of the 2 rectangles on the left and right side.
8*7 (2) = 112 (Both rectangles in total)
Now lets find the rectangles on the front and back.
13*7 (2) = 182
Now, the top and bottom ones. 
13*8 (2) = 208
Add them all together.
112+182+208 = 502
The surface area is 502.
        
                    
             
        
        
        
It's b. You have to times $4 by 6 to get $24. Then you take it away from $30 to get the change so $6
