Question

1. 4.2 l = ______ cm³
2. 0.35 km = ______ m
3. 2.3 l = ______ ml
4. 4.5 yds = ______ in
5. 50 mm = ______ km
6. 150 mg = ______ g
7. 150 kg = ______ g
8. 23 ml = ______ l
9. 0.156 g = ______ mg
10. 1.25 l = ______ ml

Explanation:

Step1: Recall volume conversion

We know that 1 L = 1000 cm³. So, 4.2 L = 4.2×1000 cm³ = 4200 cm³.

Step2: Recall length conversion

Since 1 km = 1000 m, then 0.35 km = 0.35×1000 m = 350 m.

Step3: Recall volume conversion

As 1 L = 1000 mL, 2.3 L = 2.3×1000 mL = 2300 mL.

Step4: Recall length conversion

Given 1 yd = 36 in, 4.5 yds = 4.5×36 in = 162 in.

Step5: Recall length conversion

1 km = 1000000 mm, so 50 mm = 50÷1000000 km = 0.00005 km.

Step6: Recall mass conversion

1 g = 1000 mg, then 150 mg = 150÷1000 g = 0.15 g.

Step7: Recall mass conversion

1 kg = 1000 g, so 150 kg = 150×1000 g = 150000 g.

Step8: Recall volume conversion

1 L = 1000 mL, so 23 mL = 23÷1000 L = 0.023 L.

Step9: Recall mass conversion

1 g = 1000 mg, so 0.156 g = 0.156×1000 mg = 156 mg.

Step10: Recall volume conversion

1 L = 1000 mL, so 1.25 L = 1.25×1000 mL = 1250 mL.
