Here 6x4 small cubes are there so from top view from one side 2 small cubes and from another side 2cubes that is total 4cubes from top view and from bottom view their are 4cube total 8 cubes which are having only two colors black and green,those are removed from the total number of cube that is 24-8=16.

So ans is 16 cubes

All no of cubes which colored by green and black both = 8.

Because black colored in left and right both sides,

When we remove these two sides we will have only. 16 small cubes.

Those colored only with red & green.

Do you understand shilpi.
