Sebuah kubus memiliki luas permukaan sebesar 294 cm². Tentukan panjang sisi kubus tersebut!

Rani Maharani

Soal:

Jawaban:

Luas permukaan kubus = 6s²

294 cm² = 6s²

s² = 49 cm²

s = 7 cm

Pembahasan:

Dalam soal ini, kita diminta untuk mencari panjang sisi sebuah kubus yang memiliki luas permukaan sebesar 294 cm². Luas permukaan kubus dapat dihitung dengan rumus Luas Permukaan = 6s², di mana s adalah panjang sisi kubus. Maka, dengan substitusi nilai luas permukaan yang diberikan, kita dapat menghitung besarnya s. Dalam hal ini, panjang sisi kubus tersebut adalah 7 cm.
