Solution :

We know, density is :

$density = \dfrac{mass}{volume}$

Let, the thickness of foil is x cm.

So, volume is :

$V = l\times b\times h\\\\V = 5\times 4.5 \times x\\\\V = 22.5 x$

Putting all these value in density formula, we get :

$2.70 = \dfrac{0.225}{22.5x}\\\\x = \dfrac{0.225}{22.5 \times 2.70}\\\\x = 0.0037 \ cm$

Hence, this is the required solution.
