We want to design a rectangular box without a lid with a volume
of 64000 cm^3. Find the dimensions that maximize the surface area.
Using Lagrange Multipliers
Can you explain your reasoning pls
ANSWER :
Find the dimension that maximize the surface area.
Let the length =x , width=y, height= z



Toget max surface area we will use
Lagranges multipliers
and




so,


Puting this relation is






To get max surface area the direction is
