What does this notation signifiy?

[omagdon7]

I have a problem asking me how many grams of aluminum are needed to make a line of dislocations from some point A to B is the dislocation density is 10^10cm/cm^3 does this mean for each cubic centimeter of aluminum that there are 10^10cm worth of dislocation length? This is what I suspect but I don't want to foul it up on assumptions.

I believe that's correct. I think however, it is more common to use the units of number per area (lines per cm^2).

The notation "10^10cm/cm^3" in this context represents the dislocation density of aluminum. This means that for every cubic centimeter of aluminum, there are 10^10cm worth of dislocation length. This is a measure of the concentration of dislocations within the material. Essentially, it tells us how many dislocations are present in a given volume of aluminum. It is important to note that this is an average value and the actual distribution of dislocations may vary within the material. It is always important to clarify and confirm any assumptions when solving problems in order to avoid errors.
