not enough information.
Is the top of the T made up of 3,4 or 5 cubes?
If 4, is the vertical centered to cover 2 cubes?
What does "how many cubes have exactly for blue faces?" mean? Did you mean four faces?
Wouldn't you have four faces only at the ends?
So no matter what, I would say there are only 3.
Eight one-inch cube are put together to make a “T”. If the complete figure is painted blue, how many cubes have exactly for blue faces?
How are the remaining cubes painted?
