Question

The pile of papers is
6.5 mm thick and it consist
of 100 sheets of paper
dimensions
21.5 cm x 29.7 cm. The
density of paper is
1.20. Find the mass of
one sheet of paper.​

Answer 1

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

d = M/V

M = Vd

V=( 21.5 cm x 29.7 cm ) * (0.65 centimetre)

=415.05 cm^3

M= 415.05 cm^3 * 1.20

=498.06 g/cm^3
