I think this is the answer
        
             
        
        
        
Assuming you want them multiplied
f(x)*g(x)=(3x+5)(x^2)=3x³+6x²
        
             
        
        
        
Answer:
1. -18x+6
multiply everything inside with the number outside the bracket 
2. -18x-6
same as number one 
3. 18x-12
same as number one 
4. -18x-6
same as number one 
for 5 I can't see it well but it should be similar 
you just need to substitute what's outside the bracket to what Is inside the bracket 
 
        
                    
             
        
        
        
If you want to find the volume, multiply the area of the base by the height. In this problem it would be 888*555, which is equal to 492,840
