100 cubes I LEARNED THAT IN 1ST OR SECOND GRADE who wouldn't know that?
3 cubes x 3 rows = 9 cubes
24 cubes would be it.
13 cubes 4,9,16,25,36,46,64,81,100,121,144,169,196
Depends on the size of the cubes.
Coal cubes: 0. Sugar cubes: 0 Painted cubes: maybe some of them.
Assuming that the cubes are 1x1x1, there will be one thousand cubes in the larger cube.
