The characteristic length of a cube refers to the length of a side of a cube. Since the length of all the sides of a cube are the same, the characteristic length refers to all sides.

The characteristic length of a cube refers to the length of a side of a cube. Since the length of all the sides of a cube are the same, the characteristic length refers to all sides.

Characteristic length is the ratio of volume of the body to cross-sectional area perpendicular to the direction of heat flow.Ls=characteristic length.Ls=V/A.

The answer will depend on what characteristic of the thumb you wish to measure: length, width, mass, volume, resistance to pressure, etc.
