V = s³
1728 = s³
s = ³√1728
s = ³√12³
s = 12 cm
-----
L = 6 × s × s
L = 6 × 12 × 12
L = 6 × 144
L = 864 cm²
Jawaban:
Diketahui :
Volume : 1.728 cm^3
Ditanya :
Luas permukaan ?
Jawab :
Langkah 1, Kita harus mencari panjang rusuk kubus terlebih dahulu.
S = √V^3
S = √1.728^3
S = 12 cm
Langkah 2, menghitung luas permukaan kubus.
L = 6 x s x s
L = 6 x (12 x 12)
L = 6 x 144
L = 864 cm^2
