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
