Convert 74 m² into cm².
Note
Since 1 m = 100 cm, then 1 m² = 100 × 100 = 10,000 cm². Therefore, 74 m² = 74 × 10,000 = 740000 cm². In mensuration, area and volume conversions are different from simple length conversions. For square units, square the conversion factor; for cubic units, cube the conversion factor. So the correct choice is 740000 cm².
