Let the side of the cube=a 
So the volume will be=V=a³
Then surface area of the cube will be=6a²= =
 = 
The above expression showing surface area as a function of Volume. (Answer)
 
        
             
        
        
        
We start qt 72 degrees, 
3 1/5 = 16/5 = 3.2 x 10 minutes = 32 degrees.
72 + 32 = 104 degrees. 
Cool Time:
 4 2/7 = 30/7 = 4.28571429 x 7 minutes = 30 degrees.
104 - 30 = 74
So we went from 72 to 74 degrees, that is a 2 degree difference. 
This is what i got, i hope i understood the question correctly.v
        
             
        
        
        
The perimeter would just be the equation that they provided to you multiplied by 3 because a triangle has 3 sides, and it is an equilateral triangle, so every side is the same. You do the distributive property to solve the equation and get your final answer.
