The Density of Iron is 7.874 g/cm^3. SO ...
2000g/7.874g/cm^3 = 254 cm^3
You measure its mass and volume and then density = mass/volume.
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.
You don't need the mass to get the volume. Your cube's volume = 1*2*3 = 6 cubic metres.
Calculating mass is near enough impossible: it has to be measured. You can measure its volume and then if you know its density you can work out the mass. However, that requires you to know that the cube is solid and of uniform material. I am not aware of any non-destructive method of doing so.
This question cannot be answered without knowing the mass of the cube. Also, the volume of the cube cannot be 8 cm which is a linear measure.
You measure its mass and volume and then density = mass/volume.
To determine the mass of Iron, its density is required. The formula used is Volume x Density = Mass. Assuming the Iron is pure and in solid state with a density of approximately 7.87g/cm3 at room temperature, its mass is around 51.2g.

To find the mass of a cube by multiplying the density times the volume of the cube. The volume can be found by multiplying the height times the height times the length.
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

Depends what metal. If I might add to the above, you cannot calculate the density of a substance without knowing its mass (weight) and its volume, since density is mass per unit volume. On the other hand, if you know the type of metal, and that it is pure, you can simply look up the density in a table since the density of all substances is constant for that substance, regardless of the weight or volume of the sample.
