How do you find the density of an object if you know its mass and volume?
Divide the object's mass by its volume. (D = m/v.)

If a rock displaces 45 mL of water what is its volume in cubic centimeters?
45

Will an object sink or float if it displaces an a mass of water the same as its mass?
It will float.

500
What is the density of a rock that has a mass of 500 g and a volume of 50 cubic centimeters?
10 g/cm^3

How do you find the volume of an object with a regular shape?
Measure its length, width and height and multiply them all together. (L x W x H)

Why does placing ice in a glass first and then adding the beverage prevent spillage?
The ice displaces the liquid as the latter is added to the glass rather than displacing the beverage that is already in the glass and possibly causing some of it to spill over the top.
500
What is the Archimedes Principle?
The amount of weight lost by an object in water is equal to the weight of the water it displaces. (Buoyancy is related to displacement.)
