Answer : 3.4
Explanation: 12.6 x 15.2= 191.52
 651.168 / 191.52 = 3.4
        
             
        
        
        
Answer:
WHA
Step-by-step explanation:
 
        
                    
             
        
        
        
The angle is 80 degrees. The measure of an angle is the exact same as the angle measure of the included arc, so that makes angle BAC 80 degrees
        
             
        
        
        
Let
x-------> the length side  of the original cube
we have

Divide by  both sides
 both sides

The system of equations is equal to
 --------> equation
 --------> equation 
 --------> equation
 --------> equation 
using a graphing tool
see the attached figure   
we know that
the solution of the system of equations is the intersection both graphs
therefore
the solution is 

therefore
<u>the answer is</u>
