The density is the mass divided by the volume. Divide 405 by 0.15 to get the density in kg/cubic-meter.

### The volume of a piece of metal is 22.4m3,and the mass is 675.3kg.what is the density in kg/m3

Density is the mass/1m3.

We can set this up in a ratio.

675.3kg x
---------- = ---------
22.4m3 1 m3

Since most of us don't like fractions, let's multiply both sides by 22.4.

We get 675.3 = 22.4 * x

To get x by itself, we divide both side by 22.4.

I get 30.1kg/1m3.

Good luck,

Paul

### Convert kg to cubic meters

Kilogram is a unit of mass (or weight). Cubic meter is a unit of volume. There is no direct conversion, as it depends on the density.

As an example. consider one kg of lead and one kg of feathers, The feathers would require much more volume.

### Is diameter is 3000km and the mass is 16 times the mass of the sun, what is the density of the disk

Hi,

Density is mass divided by volume.

Mass of the Sun is 1.989E30 kg, in exponential notation, where we have to move the decimal, in this case, 30 places to the right.

16 times the mass of the sun is 31.824E30 kg or 3.1824E31 kg.

Volume of the disk is 4/3 pi r ^ 3, where ^ means raised to the power of.

First, we have to take the diameter of 3000km and divide by 2 to get a radius of 1,500km. I get a volume of 14137166941.15 or 1.4137E10 km^3.

Now, dividing the mass by the volume, we get the density.

Good luck.

### How to calculate density

density is defined as the ratio of the mass of a substance to the volume occupied by that substance.
To represent density one use the Greek letter RHO (looks like a rounded p)
RHO= mass/volume
Unit of density is gram/ cm^3 or kg/m^3
Relative density is the ratio of the density of a substance to the density of pure water (at about 4 degrees Celsius). In this relation both densities must be expressed in the same units.

### 1600 cubic feet equal how many pounds.

A cubic foot is a unit of volume. A pound can be a unit od mass (weight) or a currency. Either way a volume cannot be converted into a mass nor a currency.
If you are doing homework read carefully the question to figure out what substance they are talking about.
Once you know the substance look up its density or specific gravity and do the calculation
mass (in pouunds) =density (in pounds per cubic foot) * volume (in cubic feet)

As you see, if you know the density (specific gravity) in pounds per cubic foot, you can calculate the mass of any volume of that substance (in cubic feet).

And please, never try to convert a volume into a mass.

### How to convert mass(kg) of fuel product to Litres

To convert mass to volume(which litres is a unit for), you'll need the fuel's density. The units for the quantity is mass/volume, often kg/m³ or similar. To get the volume, divide the mass by the density: kg/(kg/m³)=m³. Since 1000 litres is equivalent to 1 m³, you'll need to multiply by a thousand to get the answer in litres.
