We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architec...ture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry. (05:43)[more]

Volume is a measurement in the 3rd dimension. This means that it not only has width and height, but it has depth as well. Let's watch this video in which we get a great explanation of how we measure volume. (07:50)

In this video from Curious George, students are engaged in a classroom activity that introduces them to volume. Using cubes, the students learn that volume is the amount of space that something takes up and that, no matter how they are configured, ob...jects made using the same-sized parts will have the same volume. Closed caption included. Run time 01:27.[more]

To find the volume of an object in cubic feet, multiply the height, the length, and the width together and convert the resulting value into feet if necessary. The instructor uses a document camera to aide his lecture and model examples. (02:05)

This video begins with an instructor finding the volume of a small cube. He then proceeds to demonstrate estimating the volume of small case by using cubes. This video provides a visual for students learning the concept of volume. (02:42)

Investigate rectangular prisms and the formula used to find their volumes. Practice finding prism volumes and examine real world applications of this concept.

The instructor demonstrates how to find the volume of a cylinder using the formula. Examples model determining the radius and height of the cylinder and then plugging these values into the formula. The instructor walks the learner through the compu...tation process step by step. (03:17)[more]
