Answer:
[tex]360in^2[/tex] is your surface area
Step-by-step explanation:
I attached a picture on how to label the box.
The surface area is all the areas of the like shapes combined.
Since there are four like rectangles and two like squares it can be written like this:
[tex]A=2l_1w_1+4l_2w_2[/tex]
(l1w1 can be used for the squares and l2w2 can be used for the rectangles).
Now it's a matter of plugging in values.
[tex]A=2(6)(6)+4(12)(6)\\A=2(36)+4(72)\\A=72+288\\A=360in^2[/tex]
