Introduction: It is not hard to measure the density of an object. If you can find the mass
and the volume it is easy to find density because density is mass divided by the volume.
In this lab we have 10 cubes of varying density and we are going find the density and
order the cubes from least dense to most dense.
Hypothesis: Using a ruler and a Triple Beam Balance we believe we can find the density
of the cubes of unknown material and order them from least dense to most dense.

Procedure:
1) Using a Triple Beam Balance to find the mass of each cube and record the data in
the table on the back of this sheet.
2) Using a ruler measure the length, width, height of each cube in centimeters and
record it in the data table on the back of this sheet.
3) Using a calculator find the volume of each cube and put it in the appropriate place
in the table on back.
4) Using a calculator find the density of each using the formula d = m/v
Analysis:
Write the order of cubes from least density to greatest density:
How could this lab be changed to improve it?
