"The density is 3,000 kg per cubic meter." That tells you that every cubic meter of it has 3,000 kg of mass.
There are 6 cubic meters in 6 cubic meters.
Each cubic meter has 3,000 kg of mass.
So in 6 cubic meters, there are (6 x 3,000) = 18,000 kgof mass

As written the question is incomplete as: tonnes are a measure of mass; whereas cubic meters are a measure of volume. However, mass and volume are related for every substance by density: density = mass / volume → volume = mass / density. So if you know the density of the substance that makes up the 10,000 tonnes in tonne/m³ and divide it into the 10,000 tonnes you will get the volume in cubic meters that the substance occupies.
mass = volume x density. The units, of course, have to be compatible - for example, if the volume is in cubic meters, and the density in kilograms per cubic meter, the mass will naturally be in kilograms.
The volume is(1000)/(density of cement in kg/m3) cubic meters.
Apart from calculating the volume, you would also have to know the density. Then, multiply the volume by the density.For example: A cubical water tank has 2 meters on every side. That makes for a volume of 8 cubic meters.The density of water is 1000 kg / cubic meter, so in the end result you have (8 cubic meters) x (1000 kg / cubic meter) = 8000 kg.
density = mass/volume You need to know that mass will be measured in some form of gram, such as grams, milligrams, or kilograms. Volume will typically be measured in milliliters, liters, cubic centimeters, or cubic meters.
Volume is the space occupied by an object or substance. When working with density, volume is important because density is defined as mass per unit volume. By knowing the volume of a substance and its mass, you can calculate its density.
To compute mass using density and volume in liters, you use the formula: mass = density x volume. First, convert the volume from liters to cubic meters (1 liter = 0.001 cubic meters). Then multiply the density by the volume in cubic meters to find the mass.
To convert cubic meters to tonnes, you need to know the density of the material you are measuring. Multiply the volume in cubic meters by the density in tonnes per cubic meter to get the weight in tonnes. The formula is: weight (tonnes) = volume (cubic meters) * density (tonnes per cubic meter).
Cubic meters of what?Cubic meters are a measure of volume whereas tons are a measure of weight.Weight and volume are related by the density of the substance.
To convert cubic meters to weight, you need to know the density of the substance you are measuring. Multiply the volume in cubic meters by the density in kilograms per cubic meter to get the weight in kilograms. Alternatively, you can use specific gravity if the substance is a liquid.
It all depends upon the density of the substance. 4.8kg of Hydrogen [gas] will take up much, much more cubic meters than 4.8kg of Mercury.Cubic meters are a measure of volume whereas kilograms are a measure of weight. Volume and weight are related by density = weight ÷ volume - the lower the density, the greater the volume for the same weight!
To convert mass (kg) to volume (cubic meters), you need to know the density of the substance. Without the density, you cannot accurately convert 400 kg to cubic meters. Density is needed to convert mass to volume.
To convert kilograms (kg) to cubic meters (m³), you need to know the density of the substance. Divide the weight in kilograms by the density in kilograms per cubic meter (kg/m³) to get the volume in cubic meters. The formula is: volume (m³) = mass (kg) / density (kg/m³).
As written the question is incomplete as: tonnes are a measure of mass; whereas cubic meters are a measure of volume. However, mass and volume are related for every substance by density: density = mass / volume → volume = mass / density. So if you know the density of the substance that makes up the 10,000 tonnes in tonne/m³ and divide it into the 10,000 tonnes you will get the volume in cubic meters that the substance occupies.
mass = volume x density. The units, of course, have to be compatible - for example, if the volume is in cubic meters, and the density in kilograms per cubic meter, the mass will naturally be in kilograms.
To convert cubic meters (m³) to kilograms (kg), you need to know the density of the substance in question. Multiplying the volume in cubic meters by the density in kilograms per cubic meter will give you the mass in kilograms. The formula for this calculation is mass = volume x density.
To convert cubic meters to metric tons of fuel oil, you need to know the density of the fuel oil in metric tons per cubic meter. Once you have the density value, you can multiply the number of cubic meters by the density to get the mass in metric tons. The formula for this conversion is: Mass (in metric tons) = Volume (in cubic meters) x Density (in metric tons per cubic meter).
