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\((3×3×3=27) red cubes\). 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 (\(3×3×3\)) red cubes painted blue from outside), and joined them to form a much bigger cube\((9×9×9=729 cubes)\) 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 blue on \(1\) side Green on \(2\) sides and red on the other \(3\) sides?
