The density of the cork can be calculated by dividing its mass (10g) by its volume (40cm³). Thus, the density of the cork is 0.25 g/cm³.
The volume and mass of cork can vary depending on the size and density of the cork. On average, cork has a density of about 0.16 - 0.24 grams per cubic centimeter. To calculate the volume of cork, you can measure its dimensions and use the formula for the volume of a rectangular solid (V = l x w x h).
If you dropped a cork in a container of water, the cork will most definitely float. As to the cork is lite, like a feather and it doesnt container much mass.
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 no direct flights from Cork to Sydney or Cork to Los Angeles, so you would need to take a number of flights to get to either of them if starting from Cork. However, Sydney is much further from Cork than Los Angeles is, so it would take much longer to get there.
density of a solid is generally measured in grams/cubic centimeter. Using this information, we must determine the mass of the object, as well as it's volume/ displacement. You could measure it with something, or try submerging it in water, and record the displacement. Once the mass and volume are known the calculation is simple. The mass (in grams) is divided by the volume in cubic centimeters, or milliliters. This results in the unit of grams/cubic centimeter, or g/cc, or g/cm^3. Happy experimenting!
The density of the cork block is 40 g/cm^3. This is calculated by dividing the mass (400 g) by the volume (10 cm^3).
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.
Density = Mass/Volume = 2/8 = 0.25 g per cm3
Density = (mass) / (volume) = 2.1/14 = 0.15 gm/cc
The density of cork is about 240 kg per cubic meter.
If you mean "one kilogram", then the answer is Yes.
