By describing the formula used to calculate the volume of a triangular prism, Sal gives students practice in solving volume equations. The questions are straightforward and solved in an easy-to-follow manner. Show this to your class as...

Combine the formulas to arrive at one volume. Using the formulas for different solids, the video introduces finding the volume of composite solids. The portion of an extensive playlist on geometry works a couple of problems, one with an...

Blow up a solid by a scale factor. A section of a larger playlist on basic geometry introduces the ratios of the surface areas and volumes of similar solids. Using the ratios, the video works several examples involving similar figures.

Is prism just another mathematical term for a solid? It must be since this lesson is about volume. The teacher illustrates and explains how to find the volume of a rectangular prism and also how to find the volume of a triangular prism....

How do you find the volume of a rectangular pyramid? Watch this video and find out! In the tutorial, a lecturer works through an example problem. While she works, she describes each step and each formula necessary to solve the problem. A...

How much ice cream can you fit into a waffle cone? Sounds like geometry! Learners explore the process for calculating the volume of a right and oblique cone in this concept video. The instructor completes three examples of unique cones...

Let's move into the third dimension! Learners explore the vocabulary and notation related to three-dimensional figures. The video covers examples of pyramids, but the vocabulary is universal to all 3-D objects.

Follow along as the instructor explains what makes a solid shape a cylinder. Yes, learning the meaning of these terms: cylinder, base, curved side, curved face, congruent bases, solid, three dimensional, area, circumference, parallel,...

Pyramids: they're not just in Egypt! The segment of a large geometry playlist introduces the formulas to find the volumes and surface areas of regular pyramids. Using the formulas, the presentation works several examples to ensure your...

The solid is the same as a prism ... well, almost. The presentation makes connections between finding the volume and surface area of cylinders to prisms. Using the newly derived formulas, the portion of a large geometry playlist...

One base, triangular sides, and defined polygons are all parts of what make up a pyramid. Check out this video and see the instructor draw pictures of a variety of pyramids. She identifies the specific parts and gives them names based on...

What are the things that make a shape a cone? Here's a list of things that define a cone: base, height, vertex, radius, curved side. Are you familiar with all these terms? The teacher diagrams a cone and identifies all the components in...
