Answer:

Step-by-step explanation:

Cuboid Iron piece VOLUME = 12*4*0.4 = 19.2 m^{3}

Cube Iron pieces VOLUME  = 0.04 * 0.04 * 0.04        (since 1cm = 0.01m)

                                              = 0.000064  m^{3}

No. of cubes made = \frac{volume  of cuboid}{volume  of cube}

                                 = 19.2 m^{3} / 0.000064  m^{3}

                                 = 300,000 cubes were made of Iron

Do the same of the second question. You will get the answer
