Answer: so you do length times width times height and then you divide by two
Step-by-step explanation:
 
        
             
        
        
        
So the answer would be16*4=64
        
             
        
        
        
(a+3)(a-2)
Multiply the two brackets together
a^2-2a+3a+3*-2
a^2+a-6
Answer is a^2+a-6
 
        
                    
             
        
        
        
I think the answer is c -6.5<6.55
