Quizz [ 2/15 ]Hitunglah luas permukaan kubus yang memiliki diagonal

Berikut ini adalah pertanyaan dari erichelfredian07 pada mata pelajaran Matematika untuk jenjang Sekolah Menengah Atas

Quizz [ 2/15 ]


Hitunglah luas permukaan kubus yang memiliki diagonal sisi nya 4√2 cm.​

Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Mencari sisi:

Teorema Pythagoras

s² + s² = diagonal²

2s² = (4√2)²

2s² = 16×2

2s² = 32

s² = 32/2

s² = 16

s = √16

s = 4 cm

Mencari Luas permukaan:

L = 6 × s × s

= 6 × 4 × 4

= \boxed{\bf \color{blue}{96~{cm}^{2}}}
