If you build Swimming Pools, you need to know how much water can fit in it to market it properly.
If you own a farm with a grain silo, you need to know how much grain the silo can hold.
If you're blacktopping a driveway, you have to be able to figure out the area of the surface to charge them properly. You'll need this to know how much tar is required depending on how thin or think the coating needs to be (volume).
If you're gold-plating wire, you need to know how much gold is required so you're not wasting money.
I know you're not likely going to do all of these, and some are pretty out there, but these are real examples of how volume and area are used. -Agnes

The volume of any object is measured in cubic units of length - whatever the shape of the object. The only thing that might change are the units of length themselves: if you are imperial minded, then the volume of a model pyramid would be measured in cubic inches, that of the Egyptian or Central/South American ones would be in cubic yards. If you are SI minded, then you will prefer cubic centimetres or cubic metres.
To find the volume of a cube, just measure one edge, and then take the third power of that number (which is to say, it gets multiplied by itself 3 times, so for an edge that it 2" long, you would have 2 x 2 x 2 = 8 cubic inches). To find the volume of an irregularly shaped object, you need a graduated cylinder. You immerse the object in water, and you observe how far the water level rises in the cylinder. If the object is soluble in water, you might use some other liquid such as cooking oil.

When taking a math examination is the most important real life example.
This would be called a graduated cillender. But the ccs vary in this tool...from 100 to 1000 * * * * * A graduated CYLINDER might be a better choice!
