2. Hello, abey_27!

1 litre of paint covers an area of 12 m².
What is the thickness, in centimetres, of the coat of paint?
Give answer to 2 significant figures.
$\displaystyle \text{One liter}\:=\:1,\!000\text{ cm}^3$

The area covered is: .$\displaystyle 12\text{ m}^2 \:=\:120,\!000\text{ cm}^2$

The thickness is:. $\displaystyle \frac{1,\!000}{120,\!000} \;=\;0.008333\hdots \;\approx\;0.0083\text{ cm}$
