Which of the following is equal to 0.45 mm3? (B, right?)

4.5 x 10-7 m3

4.5 x 10-10 m3

4.5 x 10-7 cm3

4.5 x 10-3 cm3

In order to convert mm³ to m³, we use the conversion factor of 1m = 1000 mm. Also, the conversion factor of mm³ to cm³, we use the factor of 1cm = 10 mm.

= (0.45 mm³) x (1 m / 1000 mm) ³ = 4.5 x 10^-10 m³

= (0.45 mm³) x (1 cm/10 mm) ³ = 4.5 x 10^-4 cm³

Thus, the answer is letter B.
