Question

Which of the following is equal to 5.3 mm3? 5.3 x 10-6 m3 5.3 x 10-9 m3 5.3 x 10-6 cm3 5.3 x 103 cm3

Answer 1

The answer to this item is determined by using the proper conversion factors and the dimensional analysis. For the given units, meter and centimeters, the conversion from millimeters are as shown below,
 
   1 m = 1000 mm
    1 cm = 10 mm

Conversion of 5.3 mm³ to m³.
 
       = (5.3 mm³)(1 m/1000 mm)³ = 5.3 x 10⁻⁹ m³

Conversion of 5.3 mm³ to cm³.

      = (5.3 mm³)(1 cm/10 mm)³ = 5.3 x 10⁻³ cm³

The answer to this item is therefore letter B. 5.3 x 10⁻⁹ m³.
