Convert the volume 8.06 in.3 to m3, recalling that1in. =2.54cmand100cm=1m. answer in units of m3.

1 in=2.54 cm=(2.54 cm)(1 m/100 cm)=0.0254 m
Therefore:
1 in=0.0254 m
1 in³=(0.0254 m)³=1.6387064 x 10⁻⁵ m³

Therefore:

8.06 in³=(8.06 in³)(1.6387064 x 10⁻⁵ m³ / 1 in³)≈1.321 x 10⁻⁴ m³.

8.06 in³=1.321 x 10⁻⁴ m³

Independent variable is something that is changed in a experiment.
