Whether an object will sink or float?
To know this you first need to find the density of the object and the density of the fluid on which the the object shall be kept. If the density of the fluid is more than the object's density then the object will float. The object will sink if the reverse happens.
Can density determine if an object is hollow?
If we know the material that makes up the object, we will also know the density of the material. By measuring the volume and mass of the object, it is possible to find out if it is solid or hollow. This will only work if we know the material and we know the density of the material.
Why is important to know the density of an object?
so you know how much an object is denser compared to another object.
Why do you need to know the density of things?
To have knowledge about their property in the real physical world. You can also calculate how much mass an object has if you know how big it is. For example: * Low density objects floats on water. * High density objects sink in water.
When would you need to find the volume of an object?
To work out its density. or to know if you could fit it into a container of a specific volume.
What information do you have to have before you can find the Density of an object?
You have to know the object's mass and its volume. Then its density is [ (mass) divided by (volume) ].

What two things must you know before finding the density of an object?
No

Why is density important when determining what the object is made from?
Because if u know the denstiy you know what the components of the material is. By knowing that you would know the mass and volume.
How do you find the density of an object if you know its mass and volume?
Mass divided by volume.
What do you know about the density of water?
I do know about the density of water. The density of water is 1.0 grams/ millimeter. To find the density of an object, divide its mass by volume. If you have any further questions, ask me.
How can you find the mass of an object if you already know the density and the volume?
Just product of these two namely density and volume would give the mass
What would be the density of an object that has a mass of 17 g?
You don't know the density if you only know the mass. You can figure it out if you also know the object's volume.
How do you find the density of something?
you have to know the mass and volume of the object. density equals the mass divided by the volume. if the mass of something was 5 and the volume 1 the density would be 5
Why is important to know the density of an object?
so you know how much an object is denser compared to another object.
What formula would you use to find the mass of an object if you know density and volume?
Mass divided by volume equals density. or m/v = d.
