the method used to find the density of a regular solid will not work for all solids? why not? plz help, ill chose you as the best answer!

A regular solid's volume can be calculated by LxWxH. An irregular solid cannot be measured accurately enough to calculate the volume in this manner. We generally use water displacement to get the volume of an irregular solid.

Typically, surface measurements are used to determine volume, the denominator in density expressions. This will not work with all porous material.
Porous materials may have sealed pockets, which water may not even penetrate.
Either method would result in a false density, on the low side.

because a regular solid has the same density all over. but in an irregular solid there are areas of it that are "lighter" than other areas. like in a.....light bulb. in the middle of it is all air but around the edge of it is glass.

some solids will dissolve in water (if you are using a graduated cylinder).
