the number of the cubes which has atleast one face painted =number of cubes on the faces of cube
let the volume be 64unit³
so I will 64 cubes of 1 unit ³
and the length, breadth and height will be 4 unit.
the number of cube =4×4×2+4×2×4
64
I am not sure as the question has some mistakes in2 and 3line
