Astudent measures the length and mass of an object records the link is 45.2 cm convert distance measurement to the correct si base unit .4520.4524.52x10-4km17.8in

In science, physical quantities like length, weights etc are measured in units of metric or International System of units.

Some importance units are as follows:

1.Meter (m) for length.

2.Liter (L) for volume.

3.Gram (g) and kilogram (kg) for mass.

4.Degree Celsius (oC) for temperature.

5.Second for (s) time.

Given that the length of an object = 45.2 cm

SI unit of length is m

100 cm = 1.0 m

Therefore  

45.2 cm * 1 .0 m/100 cm

= 0.452 m  

c. 75.7

i think that is the right
