Answer:
1728/ 125
Step-by-step explanation:
The ratio of corresponding lengths  of the figures = ratio of the square root of their areas.
So ratio of lengths =  12/5.
Now volume is 3 dimensional  so the ratio is the cube  of the lengths 
= 12^3/5^3
= 1728/ 125.
 
        
             
        
        
        
1/8 is 12.5% so it is bigger than 12%
        
                    
             
        
        
        
Answer:
9 = x (assuming 15 is the hypotenuse)
Step-by-step explanation:
15^2 = 12^2 + x^2
225 = 144 + x^2
subtract 144 from both sides
81 = x^2
square root both sides
9 = x
