Measurement: 15 MCQs with answers

B · 1,000 cm

1 decameter = 10 meters = 10 × 100 cm = 1000 cm.

A · 56 months

4 years = 4 × 12 = 48 months; plus 8 months = 56 months.

A · 1200 m

1 km = 1000 m, so 1 km 200 m = 1000 + 200 = 1200 m.

C · 450 grams

1 kg = 1000 g, so 0.45 kg = 0.45 × 1000 = 450 g.

A · True

The source states that 1 litre = 1000 cm³.

B · False

1 meter = 1000 millimeters, not 100.

A · 0.0007 km

1 decimeter = 0.1 m, so 7 dm = 0.7 m. Since 1 km = 1000 m, 0.7 m = 0.7/1000 km = 0.0007 km.

A · 14 hours 6 minutes

846 ÷ 60 = 14 hours with remainder 6 minutes, so 14 hours 6 minutes.

A · 20 minutes 53 seconds

1253 ÷ 60 = 20 minutes with remainder 53 seconds, so 20 minutes 53 seconds.

D · 11,340 seconds

3 hours = 3 × 3600 = 10,800 s; 9 minutes = 9 × 60 = 540 s; total = 11,340 s.

C · 360 meters

1 hectometer = 100 m, so 3.6 hm = 3.6 × 100 = 360 m.

D · 43250 grams

1 kg = 1000 g, so 43.25 kg = 43.25 × 1000 = 43,250 g.

A · 2,000,000 m²

1 km² = 1,000,000 m², so 2 km² = 2 × 1,000,000 = 2,000,000 m².

D · 6007000

1 km = 1,000,000 mm, so 6.007 km = 6.007 × 1,000,000 = 6,007,000 mm.

D · 7,600,000 cubic cm

1 m³ = 1,000,000 cm³, so 7.6 m³ = 7.6 × 1,000,000 = 7,600,000 cm³.
