Bangun = Balok
Tinggi = 8 cm
Lebar = 5 cm
Panjang = Lebar = 5 cm
Luas permukaan = ...
LP = 2 × (pl + pt + lt)
LP = 2 × ((5.5) + (5.8) + (5.8))
LP = 2 × (25 + 40 + 40)
LP = 2 × (65 + 40)
LP = 2 × 105
LP = 210 cm²

Bangun = Tabung
Jari-jari (r) = 2 cm
Tinggi = 5 cm
LP = 2×phi×r (r+t)
LP = 2 × 3,14 × 2 (2 + 5)
LP = 6,28 × 2 (7)
LP = 12,56 (7)
LP = 87,92 cm²
