be reported as 83.1 or something similar - How do you read a graduated cylinder?
If given the mass, length, and diameter, you are able to determine the volume using the volume formula
of the specified shape. The use the D=m/V formula and plug in the numbers, giving you the density. -
How do you calculate density from experimental data?
