I have not seen the paper, but I think the answer should be 48.
Volume of cuboid = 3x2x1 = 6 cubic cm
Volume of individual cube = 0.5x0.5x0.5 = 0.125 cubic cm
Number that can fit = 6/0.125 = 48
Other way to think is:
Length of 3cm can have 6cubes and then width of 2cm = 4cubes, height of 1cm = 2 cubes (2layers) .. so, in total : 6 x 4 x 2 = 48 cubes
I hope this helps.
