Default Coursework advice needed

I have this Maths Coursework that I need help on.

It is about trays in a shop, a shop keeper asks a company to make some trays.

the shop keeper says that when the area of the base is the the same as the area of the 4 sides, the volume of the tray will be at a maximum.

I already know that this is true, but I want to know how to explain it.

Thanks.
