To find the density of an irregular object one has to find the mass length density( mass, length, density ) and the mass volume density( mass, volume, density ) of the irregular object. The mass of the object is found using an electronic balance a measuring cylinder a measuring tape( an electronic balance, a measuring cylinder, a measuring tape ) while the volume of the irregular object is found using a known volume measuring tape electronic balance measuring cylinder( known volume, measuring tape, electronic balance, measuring cylinder ). To find the volume of the irregular solid, one has to first insert a measuring cylinder stone known volume irregular object( measuring cylinder, stone, known volume, irregular object ) of water and gently inserting the irregular object without splashing. The new volume is recorded and this is the highest volume. The initial (smallest) volume is multiplied added subtracted( multiplied, added, subtracted ) from the final (highest) volume. This will equal the volume of the irregular object alone. The equation density=mass x volume density=volume/mass density=mass/volume( density=mass x volume, density=volume/mass, density=mass/volume ) is then used to find the density of the object.

The ruler was clamped a small distance behind the spring, making sure
that the ruler and spring hang off the desk properly.
3. The distance between the two pointers recorded. This showed the un-extended length extension new length( un-extended length, extension, new length ) of the starting position of the spring.
4. The masses extension weight( masses, extension, weight ) were gradually added and the new readings recorded, the
ending position was marked.
5. The new length original length extension( new length, original length, extension ) was found by subtracting the starting position from the ending position.
6. The results were tabulated and the force calculated
