That's not enough information. You might assume that it is, for example, a pyramid or a cone; in both cases you would need to know the base area (or the side length, or the radius, which you can use to calculate the base area). The average density doesn't help you in this problem - unless you know some other information which is not given in this problem either, such as the total mass, or anything that helps you calculate the total mass.
By dividing the mass by the volume.
density = mass/volume
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
Assuming you mean density, you might be referring to the definition of density: density = mass / volume
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
Assuming the mass and density is known, divide the mass by the density.
By dividing the mass by the volume.
mass and volume
How can you calculate surface density if the volume density is 1.4 g/cm3
Assuming I've understood what you're trying to ask: first calculate the mass, then convert that to a volume using the density.
how do you calculate density
Assuming average density of person @ 1 kg per litre then: volume (litres) = mass (kg)
Trial results are 10.045 g, 9.569 g, 10.170 g, 10.114 g, and 9.752 g. Density is 0.99704 g/mL.
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare
centroid
Unless you can calculate or measure the volume, you cannot. And even if you could you would get the average density - of the material of the ball and the air inside.
the area of the triangular face (0.5 x base x height) times the length of the prism * * * * * No. That will only give the volume which is not the same as the mass. You will either need to assume that the prism is of uniform density. In that case, you multiply its volume by the density. Alternatively, you follow Archimedes' principle to determine the density or even the weight of the prism. Then you need to convert to mass by dividing by the force of gravity. Not as easy as the first answer wrongly made it look.
