A standard 1 kilogram weight is a cylinder 48.0 mm in height and 55.0 mm in diameter. What is the density of the material?

Answer:8769 Kg/m^3

Explanation: First of all we have to calculate the volume of the cylinder so it is equal to:

Vcylinder = π*r^2*h where r and h are the radius and heigth, respectively.

Vcylinder = π*0.0275^2*0.048=1.14*10^-4 m^3

The density is defined by ρ=mass/volume

the we have

ρ=1Kg/1.14*10^-4 m^3=8769 Kg/m^3
