What else can I help you with?
What two pieces of information do you need to measure an objects' density?
you need to know its mass (weight) and volume; density is mass/volume
What other variable needs to be defined to calculate the weight of an object if the volume is given?
To calculate the weight of an object when the volume is known, you would also need the density of the material the object is made of. By multiplying the volume of the object by its density, you can determine the weight of the object.
How you calculate the weight of aluminum?
To calculate the weight of aluminum, you need to know the volume of the aluminum object (in cubic inches or cubic centimeters) and the density of aluminum (2.7 g/cm3 or 0.098 lb/in3). Multiply the volume by the density to find the weight of aluminum in grams or pounds.
Changing the mass or volume of an object changes what?
Changing the mass or volume of an object changes its density. Density is defined as the mass of an object divided by its volume, so if either the mass or volume changes, the density will change accordingly.
What two things do you need to know to work out the density of an object?
To work out the density of an object, you need to know its mass (weight) and volume. Density is calculated by dividing the mass of the object by its volume.

What is volume weight and density?
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/volume)
What is density and how is the density of a substance calculated?
Density is the weight of an object per unit of volume. For instance, the density of gold is 19 grams per cubic centimeter. To calculate the density of an object divide the weight of the object by the volume.
What detirmines the weight of an object?
The weight of an object is determined by volume, density, and gravity.
What other variable needs to be defined to calculate the weight of an object if the volume is given?
To calculate the weight of an object when the volume is known, you would also need the density of the material the object is made of. By multiplying the volume of the object by its density, you can determine the weight of the object.
Does density of an object depend on the gravity of the object?
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.
How you calculate the weight of aluminum?
To calculate the weight of aluminum, you need to know the volume of the aluminum object (in cubic inches or cubic centimeters) and the density of aluminum (2.7 g/cm3 or 0.098 lb/in3). Multiply the volume by the density to find the weight of aluminum in grams or pounds.

To work out the density of an object, you need to know its mass (weight) and volume. Density is calculated by dividing the mass of the object by its volume.
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 is the weight of an object related to its density?
They are correlated by volume weight/volume = density. For example, in a metal coin, the weight might not be much, but the volume is also very low, so it turns out that the density is high. Gases have almost no weight in a lot of volume, so their density is low.
To calculate density divide an object's?
To calculate density, divide the object's mass by its volume. The formula for density is Density = Mass / Volume. Density is a measure of how much mass is contained in a given volume.
