Luas alas kubus berbentuk persegi, maka luas alasnya adalah:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell Luas space alas end cell equals cell rusuk cross times rusuk end cell row blank equals cell rusuk squared end cell end table end style

Volume kubus adalah hasil kali dari panjang, lebar, dan juga tingginya. Namun karena panjang, tinggi, dan lebar dalam kubus adalah sama maka volumenya adalah hasil kali ketiga rusuknya.
