Answer:
784.16
Step-by-step explanation:
use the formula for simple interest = 
P(1+r)^t
so
3180(1.065)^3.5 - 3180
 
        
             
        
        
        
Answer: C
Step-by-step explanation:
A= 1/2(a+b)xh
A=1/2(7+10)x5
A=8.5x5
A=42.5
 
        
             
        
        
        
V= s^3  
a=486/6=81
s=sqrt(81)=9
v=9^3=729
the volume of the cube is 729cm^3
