Density of the material of a paper is given a 0.5 g cm^(-3) . The mass of the paper is 1 g and its length and breadth are 10 c and 5 cm, respectively. Arrange the following steps in a sequence to find the thickness of the paper. (A). The 0thickness of the paper is ("Volume of the paper (m)")/("Vlume of the paper (V)") (B) The density (d) of the material of the paper is =("Mass of the paper (m)")/("volume of the paper (V)") (C). then the volume (V) o the paper =("Mass of the paper (m)")/("Density (d) of the paper") (D). The volume (V) of the paper is=length xx breadth xx thickness of the paper.
