neither - it is area. 1 mm cubed is volume

Neither. "mm squared" refers to an area, as it is a unit of measure for two-dimensional surfaces. Density is mass per unit volume, and volume is the amount of space occupied by an object.
To calculate the density, you divide mass / volume. Since it is common to give densities in grams/cm3, convert the volume to cubic centimeters first (divide the cubic millimeters by 1000). Please note that gram is NOT a unit of weight - it is a unit of mass.
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
The volume will be 1mm cube. It is calculated by 1mm*1mm*1mm.
To find out how many 7 mm cubes fit in a volume of 3395799 cubic mm, you need to divide the total volume by the volume of one 7 mm cube (7 mm x 7 mm x 7 mm). The volume of a 7 mm cube is 343 cubic mm. Dividing 3395799 by 343 gives approximately 9905 cubes fitting in the volume.
The formula to calculate density is: Density = mass / volume. You simply divide the mass of an object by its volume to find its density. Density is a measure of how much mass is contained in a given volume.
