The question cannot be answered because the Volume cannot be Kg/cubic metre.
The Volume = (area) height.
Do you mean 900Kg/cubic metre is the Density then you can work out the volume, from the the formula
Density = Mass/volume rearrange the formula for Volume plug in the numbers and get the answer
Density is the ratio of mass to volume. Thus, the density of an object is the mass of the object divided by its volume.
Mass divided by volume gives the density of an object.
An object's mass divided by its volume gives you a measure of the object's density.
Mass divided by volume Ex. Mass: 12 Volume:3 Density:4 g/cm Hope this helps!
You can find the mass of the object by multiplying volume and density.
It is the mass of the object.
You need the object's volume and the object's mass to find the object's density. Then, you divide the object's mass by it's volume. The formula for density is d = density m = mass v = volume
Because volume is the ratio mass/density.
The density of an object is its mass per unit of volume and is determined by dividing its mass by its volume.
The object's density = (its mass) divided by (its volume)
One is the reciprocal of the other. It is more common to use "mass per volume", but in theory you could use either. If object "A" has more mass per volume than object "B", then object "B" will have more volume per mass than object "A".
Density is mass/volume. So for a given mass as the volume increases the density will reduce.
