You measure its mass and volume and then density = mass/volume.
Since mass is usually expressed in grams and volume in cubic centimeters, density is expressed in grams/cubic centimeter. For solids that have an irregular shape, the displacement method must be used to determine their volume. Choose a graduated cylinder large enough to hold the object.
If the object has a regular shape, like a cube or sphere, its volume can be calculated readily from solid geometry. Weight divided by volume gives density. For an irregular shape, one trick for finding volume is to submerge it in a calibrated container of water. The amount of increase in the volume of the water is the volume of the object. * * * * * Mosttly correct but density = mass/volume not weight/volume. Mass is not the same as weight.
Multiply the volume of the cube by its density.
Well its quite easy: Density=Mass/Volume Volume=Mass/Density SO if mass and density of a cube are given you can easily find its volume.
The unit for volume is the same, whether the shape is regular or irregular.
Density = mass/volume Density of the cube = 8g/2cm3 = 4g/cm3
33.35 grams I used the density=mass/volume formula. To get the volume of a cube you do the following: 1.2 *1.2 * 1.2=1.728 Now you plug your values in the formula: density=mass/volume mass=density*volume mass=19.3 * 1.2 = 23.16 mass=33.35 grams
That completely depends on the volume of the cube.
Volume = Length x Width x Height, for a cube and Density = Mass / Volume.
Density = Mass/Volume Volume of cube=5cmx5cmx5cm=125cm3 So 30g/125cm3=0.24g/cm3
The density is(mass of the cube)/(15.625)
