Luas alas kubus berbentuk persegi, maka luas alasnya adalah: Volume kubus adalahhasil kali dari panjang, lebar, dan juga tingginya. Namun karena panjang, tinggi, dan lebar dalamkubusadalah sama maka volumenya adalah hasil kali ketiga rusuknya. . Luas alas , maka: Rusuk Volume . Luas alas , maka: Rusuk Volume . Luas alas , maka: Rusuk Volume . Luas alas , maka: Rusuk Volume . Luas alas , maka: Rusuk Volume Sehingga diperoleh tabelnya adalah sebagai berikut:

Luas alas kubus berbentuk persegi, maka luas alasnya adalah:
