Answer:
the ratio would be 2:3 simplified 
 
        
             
        
        
        
Angles can be used to estimate the side lengths of a shape.
The letters in order of greatest to least are (a), (b) and (c)
The sum of angles at side (a) is:


The sum of angles at side (c) is:


The sum of angles at side (b) is:


So, we have:



The smaller the base angles, the longer the side.
Hence, the letters in order of greatest to least are (a), (b) and (c)

Answer:
The answer to your question is  8/3 u²
Step-by-step explanation:
Data
length of the side = 2/3
Surface area = ?
Process
1.- Calculate the area of one face
Area = side x side
-Substitution 
Area = 2/3 x 2/3
-Result
Area = 4/9
2.- Calculate the area of the cube (a cube has 6 faces)
Surface area = 4/9 x 6 
                      = 24/9
-Simplification
Surface area = 8/3 u²
 
        
             
        
        
        




The correct answer is <u><em>6.9</em></u>
Hope this helps!!!
