Heat will flow from the warmer air into the colder copper cube.
Spontaneous heat transfer always goes from higher temperature to lower temperature. The cube will warm while the air (or whatever is keeping the container at 85°C) cools slightly until thermal equilibrium is reached. If the container interior truly acts as a large heat reservoir held at 85°C, the cube will approach 85°C. If the container is isolated and its internal energy is conserved, the final temperature will be somewhere between 5°C and 85°C determined by the heat capacities of the air, cube, and container.
