Jawaban:

1. Luas = 64 cm², keliling = 32 cm

2. Luas permukaan = 600 cm²

3. Volume = 1.728 cm³

4. Luas = 48 cm², keliling = 32 cm

5. Luas permukaan = 920 cm², volume = 1.500 cm³

Penjelasan dengan langkah-langkah:

1. Luas = s × s = 8 × 8 = 64 cm²

Keliling = 4 × s = 4 × 8 = 32 cm

2. Luas permukaan = 6 × s² = 6 × 10² = 6 × 10 × 10 = 600 cm²

3. Volume = s³ = s × s × s = 12 × 12 × 12 = 1.728 cm³

4. Luas = p × l = 12 × 4 = 48 cm²

Keliling = 2 × (p + l) = 2 × (12 + 4) = 2 × 16 = 32 cm

5. Lp = 2 × (pl + pt + lt)

= 2 × (25 × 10 + 25 × 6 + 10 × 6)

= 2 × (250 + 150 + 60)

= 2 × 460

= 920 cm²

Volume = p × l × t = 25 × 10 × 6 = 250 × 6 = 1.500 cm³

semoga membantu
