Let me know if you need the steps tho.
 
        
             
        
        
        
1/4 = 2/8. Remember that. This means that 1/8 is equal to half of a month. It there is 5/8, you can add a half month for every eights. In this case, it will take 2 and a half months
Easy Way:<span>If your hair were to grow 1/4 inches a month, it would also grow 2/8 inches a month, since 1/4 = 2/8. How long with it take 1/8 (0.5/4)inches to grow? It would take a half of a month for your hair to grow 1/8 inches.
</span><span>Now that we know 1/8 inches grows in a half of a month, we add a half of a month for every eigths. Since we are trying to figure out how long it would take for it to grow 5/8 inches, we add 5 half months to get the answer of 2 and a half months. Kind of confusing, but that is the best way I can describe it.</span>

Answer:
Side length =  cm ,   Height =
 cm ,   Height =   cm  ,  Volume =
 cm  ,  Volume =  cm³
  cm³
Step-by-step explanation:
Assume 
Side length of base = x 
Height of box = y
total material required to construct box = A ( given in question)
So it can be written as
A = x² + 4xy 
4xy = A - x²
 
Volume of box = Area x height
V = x² ₓ y
V = x² ₓ (  )
 )
V =  
To find max volume put V' = 0
So taking derivative equation becomes

A = 3 
 =
 = 
x = 
put value of x in equation 1
y =  
  
y = 
y = 
So the volume will be
V =  × y
 × y
Put values of x and y from equation 2 & 3
V = 
V =
