) a cube is painted blue on all of its surfaces . it is then cut in to 27 smaller cubes of equal size . find how many smaller cubes have no color ?
if the cube is cut in to 27 smaller cubes , then number of separations made = n = 3 ( since 3 × 3 × 3 = 27 ) . number of smaller cubes with no color = ( n – 2 ) 3 = ( 3 – 2 ) 3 = 13 = 1 answer : a
volume_cube(subtract(divide(divide(27, const_3), const_3), const_2))
