If you have a caliper this is really easy. Corks are truncated cones. Measure the diameter of the cork at the top and at the bottom, average them, then calculate the volume using the average diameter.
That depends on how much cork you have. If you have a large piece, then it will have more volume and more mass. If you only have a tiny piece, then the volume and the mass will both be very small. The volume and the mass will always change together like that, in the same direction. The only thing you can always be sure of is that no matter what size piece of cork you have, the grams of mass will always be about 0.2 times the volume in cubic centimeters.
If the cork is floating, then part of it is underwater and part of it is abovewater. The part that's above water is not displacing water, so the volumedisplaced is less than the total volume of the cork.Here's a mantra that will, come in very handy if you memorize it and thenfile it away until you need it:"A sinking object displaces its volume.A floating object displaces its weight." I can't think of any way that an object in water could displace morethanits volume.
density of 1.5 cm tall and mass of 1.0 g of a cube of a cork=mass/volume of cube== 1.0/(1.5*1.5*1.5)gm/cm3=.2963gm/cm3
The density of a wooden cork stopper is about 0.25 grams per ml. This value can be important in experiments where a cork stopper is used.

We need specific measurements to calculate any volume.
Volume of a substance is measured in cubic units and is given by dividing its mass by its volume. In this case it is not possible to find the density of the cork since 2.71cm2 is a measurement of an area.

There are multiple methods as to estimate the density of irregular objects. The cork can be cut into a cylinder form. Using the equation for the volume of cylinder, and density (D = mass/volume) the cork density can be approximated.
using water displacement method
By carrying out the water displacement method
Step 1: Fill a graduated cylinder with water Step 2: Measure how much water is in the cylinder Step 3: Place the cork in the water Step 4: Measure the amount of water again Step 5: Subtract amount of water without cork and amount of water with cork regular- cork = volume of cork This method is called water displacement.
10 grams of cork would have 10g / (.24 g per cm^3) would come out to 41.666 cm^3.
It?æ is hard to find the density of a cork in water because?æ cork floats?æ in water. Density of a substance is given by its?æ mass divide?æ by its volume and since cork does not submerge, it is difficult to find its volume.
Density = (mass) / (volume) = 2.1/14 = 0.15 gm/cc
Density = Mass/Volume = 2/8 = 0.25 g per cm3
