Kubus adalah bangun ruang tiga dimensi
yang dibatasi oleh enam bidang sisi yang
berbentuk bujur sangkar. Kubus memiliki 6
sisi, 12 rusuk dan 8 titik sudut. Kubus juga
disebut bidang enam beraturan, selain itu
juga merupakan bentuk khusus dalam
prisma segiempat.
A cube is a three-dimensional solid object
bounded by six square faces, facets or sides,
with three meeting at each vertex. The cube
can also be called a regular hexahedron and
is one of the five Platonic solids. It is a
special kind of square prism, of rectangular
parallelepiped and of trigonal trapezohedron.TRANSLATE
