  • 6. Volume prisma = luas alas × t / 3
    Luas alas = Volume × 3 / t
    = 2.304 m³ × 3 / 12 m
    = 6.912 m³ / 12 m
    = 576 m² (C)
    7. Volume = luas alas × t / 3
    = 144 dm² × 8 dm / 3
    = 1.152 dm³ / 3
    = 384 dm³ (D)
    8. Volume = luas alas × t
    t = volume / luas alas
    = 300 cm³ / 20 cm²
    = 15 cm (B)
    9. panjang = 1 m → 10 dm
    lebar = 80 cm → 8 dm
    tinggi = 60 cm → 6 dm
    Volume = ¾ × (p×l×t)
    = ¾ × (10 dm × 8 dm × 6 dm)
    = ¾ × 480 dm³
    = 360 dm³ (D)
    10. Volume = p × l × t
    t = Volume / (p×l)
    = 2.700 cm³ / (25 cm × 12 cm)
    = 2.700 cm³ / 300 cm²
    = 9 cm (A)
