Density is the mass per volume of a solid, liquid or gas. The density of a material is often expressed in grams per cubic centimeters.

A common method of determining the density of a material is to use a block of it. This allows the density of the material to be accurately calculated without any error because pure aluminum is aluminium no matter how it is shaped.

To calculate the **density of aluminum foil**, first determine its volume using the formula V = mass/density g/cm

Alternatively, you can find the volume by using the formula mass of foil / (length x width x density of aluminum). This is equivalent to V x W x H where L is the length, W is the width and H is the height.

The thickness of the foil can also be determined by using the same equation. Since the density of aluminum is 2.7 g/cm

The study of cellular materials has traditionally been characterised by the relationship between relative density and mechanical properties. It has been shown that the real Youngâ€™s modulus increases with relative density whereas compressive strength decreases. This is largely due to the tightening of pore spaces during compression which leads to an increase in interlocking.
