Well, its given cubes having black and green, but it's not mentioned that it cannot have a red color, so the cubes that have black and green both colour are the cubes present in the left and right corners, which sum up to 8.
Thus remaining 16 cubes are left.
So, the answer is 16.
Thus remaining 16 cubes are left.
So, the answer is 16.

Why we include corner cubes. There are only 4 cubes with only Black and Green color. 4 cubes with Red, Black and Green colors and 8 cubes with only Green color, 8 cubes with Green and Red color.
According to Question We have to consider cubes with only Black and Green color and no other color. Right now we are considering 4 cubes (with only black and Green color) and 4 corner cubes (with all the three colors Black+Green+red) for counting total number of Black and green cubes.
So Answer should be 24-4 = 20.

The word "only" is missing.
Hence when we say black and green colored cubes.
It includes all the cubes which are black in colour and all the cubes which are green in colour.
