Answer / srawan
Since the number of smaller cubes are 125, and the area of
cube is a^3 where a is the side of the original cube, 125=
5^3. Therefore, we have all sides of the cube divided into 5
parts each.
Q-1: Cubes colored blue on one faces, red or green on the
other= 5+5=10
Cubes having four uncolored faces= 4*4*3= 48
Q-2: Cubes having red on one face and remaining uncolored=
4*4= 16.
