Question

56. Density of the material of a paper is 0.4 g 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 1

Answer:

thickness of paper is 0.03125 cm (0.3125 mm)

Explanation:

Volume = Mass / Density

V = 0.5 / 0.4

V = 1.25

Now, Volume = L × B × H

         1.25 = 10 × 4 × H

         1.25 / 40 = H

      ∴ H = 0.03125 cm
