Answer:

4. 72 m

5. 42 m

6. 66 yd

8. 18 yd

9. 200 cm

Step-by-step explanation:

3) 1 × 3 × 8 + [5 × 8 × (4-3)] = 24 + 40 = 64 yd³

4) 9 × 1 × 8 = 72 m³

5) 3 × 7 × 2 = 42 m³

6) 3 × 3 × (6 - 2) + 2 × 5 × 3 = 36 + 30 = 66 yd³

7) (7 - 5) × 7 × 3 + 8 × 7 × 5 = 42 + 280 = 322 mm³

8) 3 × 3 × 2 = 18 yd³

9) 8 × 5 × 5 = 200 cm³
