#54# one cubic centimeter cubes will have exactly one of their sides painted.

Explanation:

There are six sides of the cube and as side of cube is #5# cm and hence each side will have #5xx5=25# one cubic centimeter cubes painted.

However, all the cubes on sides and corners will have painted sides more than one as they share with adjoining sides and only #3xx3=9# one cubic centimeter cubes will have one side painted.

As there are six sides, #9xx6=54# one cubic centimeter cubes will have exactly one of their sides painted.
