Jawaban:
9600 cm²
Penjelasan dengan langkah-langkah:
volume = 64000 cm³
V = s³
64000 = s³
s = ³√64000
s = 40 cm
Maka,
Luas permukaan kubus
= 6 x s x s
= 6 x 40 x 40
= 9600 cm²
volume = 64.000 cm³
LP = ?
V = r³
64.000 = r³
r = ³√64.000
r = 40 cm
Luas permukaan = 6 × r²
LP = 6 × 40²
LP = 6 × (40 × 40)
LP = 6 × 1.600
LP = 9.600 cm²
