1.	Density of the material of a paper is o.4g `cm^(-3)`.The mass of the paper is 0.5 g and its length and breadth are 10 cm and 4 cm, respectively. Determine the thickness of the paper.
Answer» Density of paper =` 0.4 " g " cm^(-3)` Mass of paper = 0.5 g Volume of paper =` 0.5/0.4 = 1.25 " "cm^(3)` Volume = `( length xx breadth xx thickness)` Thickness =`1.25/(10xx4)=1.25/40 = 0.03125`
