You need to know the local force of gravity and the density of the object.
Divide the weight by the local acceleration due to gravity to convert to mass. Then divide the result by the density to get the volume. If you are in outer space, you have no hope because the local gravity will be 0 and division by 0 is not defined.

How do you calculate the density of a polyurethane foam?
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
How is mass and volume determined density?
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.
How do you know which objects are more dense or less dense?
Density is weight divided by volume. Weight is measured with a scale. Volume can be calculated if an object has a regular shape, using basic geometry, but if it has an irregular shape, it can be calculated using a graduated cylinder.
What is the volume of a 10 gram object if it weighs 8 grams under water?
The volume of the object is equal to the difference in weight when submerged in water and when in air, divided by the density of water. Using the formula: Volume = (Weight in air - Weight in water) / Density of water, we have Volume = (10g - 8g) / 1 g/cm^3 = 2 cm^3.
How do you find weight when you have density and volume?
To find the weight when you have density and volume, you can multiply the density by the volume to get the mass, and then multiply the mass by the acceleration due to gravity to get the weight. The formula is weight = density x volume x acceleration due to gravity.
What is the measure of matter that is weight divided by volume?
None that I know of, but mass divided by volume is density.
Is an object's density equal to its mass divided by its length?
Not exactly. Density is weight divided by volume.
Is The weight of a substance is defined as its mass divided by its volume.?
weight is different in different gavities but mass is not, volume is not involved
How do you calculate the density of matter?
Volume occupied divided by weight
Density of solid?
Density is weight (mass actually) divided by volume.
What is the mathmatical formula for finding density?
Density is weight divided by volume.
The ------ of a substance is defined as it mass divided by its volume?
weight is different in different gavities but mass is not, volume is not involved
What is the difference between percentage by weight and volume?
Percentage by weight refers to the concentration of a substance in a mixture by weight, while percentage by volume refers to the concentration by volume. Percentage by weight is calculated as the weight of the substance divided by the total weight of the mixture multiplied by 100, while percentage by volume is calculated as the volume of the substance divided by the total volume of the mixture multiplied by 100.
Why did the Archimedes need to know to work out the density of a substance?
Weight vs volume. PLace object in container already full of water. Measure volume of liquid displaced. weight object. weight divided by volume equals density
How do you calculate the denstiy of pyrite?
Compare its weight to the weight of an equal volume of water. The weight of the specimen divided by the weight of the water equals the density of the specimen.
How do you calculate density from molecular weight?
Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.
What is a Adjective for heavy?
Geologists reference a material's density in reference to it's weight. Density is the material's weight divided by the weight of an equal volume of water.
