Is the temperature inside of a metal box cooler than ambient
temperature?

I need to look. If that is so. Can be used for storing medicine and
maybe other things.

If you take the closed box from a cool place to a warm place, it will be coler than the warm place for some short time, until it equalizes.

Leave it in the sun and it's a solar oven.

No, because in the 1970's german movies about treasure and artwork thieves, they show people walking in tee shirts and shorts in the alps while frost or ice is still on the ground.
