The difference in the widths, in meters, of the human hair and the piece of sand is
m.
It is given in the question that:-
Width of a human hair =
m
Width of a piece of sand =
m
We have to find the difference in the widths, in meters, of the human hair and the piece of sand.
We know that,
Difference between the widths = Width of a piece of sand - Width of a human hair
Hence, we can write,
Difference between the widths =
m -
m
We can write,

Hence,
Difference between the widths =
m
