#Measure the [[mass]] of the [[cuboid]] using an [[Electronic Balance|electronic balance]] or [[Measuring Scale|measuring scale]].#Measure the length, width and height of the [[cuboid]] using a [[ruler]].
#Multiply the length, width and height to calculate the [[Volume (Space)|volume]].
#Use the equation <math>\rho = \frac{m}{V}</math> to calculate the [[density]] of the [[cuboid]].
====Improving [[Accuracy]]====
: Use a [[ruler]] with a higher [[resolution]].
: Use an [[Electronic Balance|electronic balance]] with a higher [[resolution]].
: Use a larger [[cuboid]] to reduce the [[uncertainty]] caused by the [[resolution]] of the [[Measuring Instrument|measuring instruments]].
