More Game Cubes

Aviv has game cubes, where two opposite faces of each are painted red and the rest are blue.
Aviv glued together a `3 xx 3 xx 3` cube from the game cubes. Then his friend Kfir came and calculated the total red area on the surface of the large cube.
What is the largest result Kfir can get?
