Answer:
640 cm³
Step-by-step explanation:
Each prism has a volume of (4 cm) (4 cm) (20 cm) = 320 cm³.
There are two prisms, so the total volume is 640 cm³.
 
        
             
        
        
        
R - 6m = n.....add 6m to both sides
r = n + 6m <==
        
             
        
        
        
Since the volume of a rectangular prism is V=lwh, we can isolate for h to obtain that h=V/(lw).
So, for the first prism, the height is 117/(4*6.5) = 4.5
Similarly, for the second prism, the height is 175.5/(6.5 * 4) = 6.75
So, the difference in heights is 6.75-4.5=2.25 = 2 1/4 inches
