Step-by-step explanation:
From the example given, Since an electronic company wants to differentiate  their cell phones quality to the cell phones from their three main competitors.
If ANOVA is used to determine the average number of defects, then the treatment  should be defined for the four companies because it is more interested in comparing the quality among the different companies.
 
        
             
        
        
        
You can do this !
The rectangular prism has 
                   -- length = 10 cm
                   -- width  =  7 cm
                   -- height =  3 cm.
-- The area of the top and bottom is  (length x width)  each.
-- The area of the left and right sides is  (length x height)  each.
-- The area of the front and back is  (width x height)  each.
There.  I just laid out all the schmartz you need to answer this question.
The rest is all simple arithmetic, and you're perfectly capable of turning
the crank and getting the answer.  You don't need anybody else to do 
that part for you.
Don't forget your units.  The area of each flat face is (cm) times (cm),
and that product will be some cm² , for area.

5, 20, 80, 320, 1280, 5120, 20480, 81920, 327680, 1310720, 5242880, 20971520
The 12th term would be 20,971,520 
Everything is being multiplied by 4 each time
