If a piece of aluminum foil weighs 0.225 grams and has the length of 5.00 cm, and a width of 4.50 cm, Find the thickness of the foil in centimeters. The density of aluminum is 2.70 g/cm^3.

Solution :

We know, density is :

Let, the thickness of foil is x cm.

So, volume is :

Putting all these value in density formula, we get :

Hence, this is the required solution.
