Question

A cube is painted blue on all faces. It is cut into 125 smaller cubes of equal size. How many cubes
are painted on one face only ?

Answer 1

Answer:

54  cubes are painted on one face only

Step-by-step explanation:

A cube is painted blue on all faces. It is cut into 125 smaller cubes of equal size

5 * 5 * 5  = 125

Now Each Face has 5 * 5  cubes

but lines at Edge will have more than one face painted blue

so 3 * 3 = 9 cubes on each face will be be painted blue

there are total 6 faces

9 * 6 = 54 cubes

54  cubes are painted on one face only
