Can someone pls help me I’m so confused!!

Explanation:

you multiply all 3 sides to get volume then to get the density you divide the mass by volume dont forget units also check pic  

In order to rank these measurements correctly, it would be useful to convert the values to the same units. For this case, we convert them to meters. We do as follows:

1mi = 1609.34 m
10m = 10 m
1x10^11nm = 100 m
50in = 1.27 m

Therefore, the correct ranking would be as follows:

1mi, 1x10^11nm, 10m, and 50in.
