Jawaban:

320 cm²

Penjelasan dengan langkah-langkah:

Luas permukaan kubus = 6 x s x s

Lp kubus = 6 x 4 x 4

Lp kubus = 96 cm²

Luas permukaan balok = 2 [(panjang x lebar) + (panjang x tinggi) + (lebar x tinggi)]

Lp balok = 2 [(12 x 4) + (12 x 4) + (4 x 4)]

Lp balok = 2 [48 + 48 + 16]

Lp balok = 2 [112]

Lp balok = 224 cm²

Total = Lp kubus + Lp balok

Total = 96 cm² + 244 cm²

Total = 320 cm²
