Luas balok = (12 * 7) * 2 + (12 * 6) * 2 + (6 * 7) * 2 = 396 cm²
Volume balok: 12 * 6 * 7 = 504 cm³
Kalau di cek di kalkulator, pasti benar! ✅
Diketahui:
t = 7 cm
p = 12 cm
l = 6 cm
Ditanya: Luas Permukaan Balok?
Cara:
LpB = 2 x (p x l) + (p x t) + (l x t)
LpB = 2 x ( 12 cm x 6 cm) + ( 12 cm x 7 cm) + ( 7 cm x 6 cm)
LpB = 2 x ( 72 cm + 84 cm + 42 cm)
LpB = 2 x 198 cm
LpB = 396 cm²
