Astack of 500 sheets of paper measuring 28 cm x 21 cm is 44.5 mm high and has a mass of 2090 g. what is the density of the paper in grams per cubic cm?

The density of stack is

Explanation:

To calculate the volume of cuboid, we use the equation:

where,

V = volume of cuboid

l = length of cuboid = 28 c

b = breadth of cuboid = 21 cm

h = height of cuboid = 44.5 cm

Putting values in above equation, we get:

To calculate density of a substance, we use the equation:

We are given:

Mass of stack = 2090 g

Volume of stack =

Putting values in above equation, we get:

Hence, the density of stack is

a

explanation:

the atomic mass is the bottom number on the element.
