Cube gathered for a meeting

Geometry Level 3

I had a red cube like this

I took 26 more such cube(red from all sides) and joined them to form a bigger cube \((3\times3\times3=27) red cubes\). And painted it blue from all of its six sides from the outside, like this.
Now , I took 26 more such cubes (with each cube having (\(3\times3\times3\)) red cubes painted blue from outside), and joined them to form a much bigger cube \((9\times9\times9=729 cubes)\) and painted it Green from all its six sides from the outside like this:

How many smaller cubes \(the\) \(one\) \(that\) \(I\) \(had\) \(at\) \(the \) \(starting\) are painted green on 1 side and red on the other 5 sides?
