## Volume

We live in a 3 Dimensional World.

##### If you have WebSpace installed, click on one the figures shown above.

**Volume is the amount of space an object occupies.**

### Case I:

The volume of an object can be calculated using mathematical equations. The volume of a cube can be found using the formula V=(side)x(side)x(side)

**What is the volume of the metal cube shown here?**

### Note:

The side of the cube is approximately 3.1 centimeters. How many inches does this
convert to?

### Case II:

It is also possible to find the volume of an object by measuring the volume of water that it displaces.

**What will happen when we lower the above metal block slowly into a graduated cylinder containing
water?** *Click on the image and find out if your correct.*.

**What was the amount of water displaced by the object?**

Please enter your answer in the space provided.
*If you need a calculator one is available. Click on calculator in the left frame.*

Notice that both methods give fairly accurate values for the volume of the
cube. Why are the volumes not exactly the same for the two methods used?

### How does the volume of a cube vary with the area of one of its surfaces? With
the length of one side of the cube?

Type in any value for length and then click on one of the other boxes.
