摘要

The cube structure toy with a volume of 1000 cm3, for use as a learning aid, is assembled from separate bricks (1-3). The bricks have a constant thickness, but a variable length and width as a whole number multiple of the thickness, to be brought together with surface contact between them. At least one brick is of a different material from the others.
