  • only problem i have is that 24 inches squared is the area,and the way you drew it out it was 24x24 giving an area of 576 inches squared... at least thats how i see it

  • How the hell do you dislike a KHAN video????????

  • Rather than take the second derivative to determine if it's a maximum, why not just plug 3 and 5 into V' for x? You will see that it is positive at 3, and negative at 5. If the equation goes from a positive to a negative at 4, than this would be a maximum on V.
