Introduction
The purpose of the experiment is to show how to use the different measuring tools that can affect the
precision of the data. Also, to learn how to use the concepts of the significant figures, the experimental
error and some methods of error and data analysis in your experimental measurements.
Theory
The equation is to determine the volumes of the calculated measurements
ρ =
M
V
where m is the in kilograms, V is the volume in cubic meters, and ρ is the density in units of kilogram per
cubic meters
For a cube the volume is
V = LWH
where L is the length, W is the width and H is the height.
For the sphere its formula to determine the volume is
v =
4
3
π r
3
where V is volume of the sphere, and r is the radius of a sphere, it is the distance between its center and
any point on its surface.
For the cylinder its formula to find the volume
π r
2
h
Procedures
1. We first started by measuring the metric stick, the Vernier caliper and the micrometer caliper
also the beaker to figure out the least count and the estimated fraction and figuring out the
measurements of them
2. We started measuring just one single piece of paper from the lab manual and we did it four
times, every time a different person would do it. We did this with the micrometer

3. After that we started to measure 10 different pieces together of paper from the lab manual, we
