Answer : 72 blocks
To find the answer, you have to find the volume of the prism. To find the volume you multiply the length, width, and height. 
6 x 3 x 4 = 72
This gives you 72 blocks.
        
             
        
        
        
Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657
 
        
                    
             
        
        
        
Using the critical point concept, it is found that a = -3 and b = 7.
<h3>What are the critical points of a function?</h3>
- The critical points of a function are the values of x for which:

In this problem, the function is:

Hence, the derivative is:

Then:







Since the critical point is at x = 2, we have that:




Then:

Critical point at (2,3) means that when  , then:
, then:

Answer:
   5
Step-by-step explanation:
Let f represent the number of friends. Their total earnings are ...
   21f = 105
   f = 105/21 = 5 . . . . . divide by the coefficient of f
There are 5 friends in the group.
