1. The problem is to convert 28 mm³ into cubic centimeters using the conversion factor 10 mm = 1 cm. 2. First, understand that 1 cm = 10 mm means that 1 cm³ = (10 mm)³ = 10³ mm³ = 1000 mm³. 3. To convert from mm³ to cm³, divide the volume in mm³ by 1000 because 1 cm³ = 1000 mm³. 4. Calculate: $$28 \text{ mm}^3 = \frac{28}{1000} \text{ cm}^3 = 0.028 \text{ cm}^3.$$ 5. Therefore, 28 mm³ is equal to 0.028 cubic centimeters.
