Penyelesaian:

21.) Jawaban: A.28 buah

Banyak kubus satuan yg terkena cat pada dua sisinya:

• = 2 (12 + 2)
• = 2 (14)
• = 28

22.) Jawaban: C.1.800 cm³

Volume bangun tsb:

• V = (p × l × t) + (⅓ × la × t)
• V = (15 × 10 × 8) + (⅓ × 15 × 10 × (20 - 8))
• V = 1.200 + (5 × 10 (12))
• V = 1.200 + (50(12))
• V = 1.200 + 600
• V = 1.800 cm³
