Answer 2

Answer:

The area density (also known as areal density, surface density, superficial density, areic density, mass thickness, column density, or density thickness) of a two-dimensional object is calculated as the mass per unit area. The SI derived unit is: kilogram per square metre (kg·m−2).

In SI base units: m−2⋅kg

SI unit: kg/m2
