Since they are multiples if 12
The possibilities are
12, 12, 156
12,24,144
12,36,132
12,48,120
12,60,108
12,72,96
12,84,84
24,24,132
24,36,120
24,48,108
24,60,96
24,72,84
36,36,108
36,48,96
36,60,84
36,72,72
48,48,84
48,60,72
60,60,60
Hence the probability is 1/19 or 0.0526
 
        
             
        
        
        
Answer:
Y=mx+b
Step-by-step explanation:
mx = slope
b = intercept (the place where the line hits the y axis)
 
        
                    
             
        
        
        
You can seperate the prisms then use the formula l*w*h which for the one on top u get V=20 and for the other one is 48 so 20+48= 68 so the volume of the prism is 
(☞゚ヮ゚)☞ 68 ☜(゚ヮ゚☜)
 
        
                    
             
        
        
        
100 thousands is the answer good luck!
        
             
        
        
        
So when you have data given this kind of form... you should convert to decimal first.
So that would be:
a ≈ 2.12
b = 3.5
c = 2.5
Now just place the simple perimeter formula, and sum all sides.
