Can you explain your reasoning pls

Solutions

Expert Solution

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
