Question 169027
A cube has an angle length of 4 inches. The cube is painted red all over and then cut into 64 cubes of edge length 1 inch. How many of these cubes have one face painted red?
------------------
I don't know what "angle length" is.
---------------------------------
If you meant the length of a side:
On each face, the cubes will have more than one side painted.  Each face is cut into squares 4 by 4, so the inside squares (2 by 2) will be the cubes with only one side painted.  There are 4 on each of the 6 faces, so 
6*4 = 24
