## Students will review:

This chapter helps students review the concepts in a perimeter, area and volume unit of a standard high school math course. Topics covered include:

- Three-dimensional figures in geometry
- Perimeter of triangles and rectangles
- Area of triangles and rectangles
- Area and circumference of circles
- Volume of cylinders, cones and spheres
- Volume of prisms and pyramids
- Surface area of cubes and rectangular prisms
- Surface area of cylinders
- Surface area of pyramids
- Area of complex two- and three-dimensional figures
- Perimeter of three-dimensional rectangular solids

### 1. Perimeter of Triangles and Rectangles

Without realizing it, we calculate and use the perimeter of triangles and rectangles in regular everyday situations. Learn more about the perimeter of triangles and rectangles in this lesson, and test your knowledge with a quiz.

### 2. Area of Triangles and Rectangles

How do you find out the area of rectangles and triangles? Learn how in this lesson! We'll look at the formulas, then practice solving problems for each shape.

### 3. Circles: Area and Circumference

Understanding how to calculate the area and circumference of circles plays a vital role in some of our everyday functions. They serve as the foundation for operating with three-dimensional figures. Learn more about the area and circumference of circles in this lesson.

### 4. Volume of Cylinders, Cones, and Spheres

In this lesson, we'll learn about the volume formulas for cylinders, cones and spheres. We'll also practice using the formula in a variety of real-world examples where knowing how to calculate volume is helpful.

### 5. Volume of Prisms and Pyramids

In this lesson, we'll learn about prisms and pyramids. We'll look at the different types of prisms and pyramids, as well as practice calculating volume for each shape.

### 6. How to Find Surface Area of a Cube and a Rectangular Prism

After watching this video lesson, you will be able to use the formula for the surface area of a rectangular prism. You will know what measurements you need to use it and how you can apply it to a cube as well.

### 7. How to Find Surface Area of a Cylinder

Watch this video lesson to learn the formula you can use to find the surface area of a cylinder. Learn the measurements that you'll need as well as how to use them.

### 8. How to Find Surface Area of a Pyramid

In this video lesson, we will learn how to take any pyramid, whether it's a pyramid in Egypt or a little toy pyramid, and calculate how much paint we will need to paint it. Learn the formula and what is behind it.

### 9. Applying Scale Factors to Perimeter, Area, and Volume of Similar Figures

How do shapes change sizes yet retain their proportions and similarities to other shapes? In this lesson, we'll look at what a scale factor is and how to apply it. We'll consider scale factors with regards to three different aspects of similar shapes: perimeter, area and volume.

### 10. Area Method: Slope & Examples

This lesson discusses the Slope Area Method to calculate the flow of a waterway at a particular point. There is more than one way to calculate this information, but the Slope Area Method has its advantages, especially for man-made waterways.

### 11. Finding the Area of a Cylinder: Formula & Example

In this lesson, you'll review the definition of a cylinder and learn how to find its surface area. Then, you can test your new knowledge with a brief quiz.

### 12. How to Calculate the Volume of a Cube: Formula & Practice

In this lesson, you will explore the formula used to calculate the volume of a cube. You will also gain a conceptual understanding of volume and appropriate units to use. Then test your knowledge in a brief quiz.

### 13. How to Find the Surface Area of a Cube

In this lesson, we'll look at what makes cubes unique among three-dimensional shapes, and we'll put that uniqueness to use in finding an easy way to find the surface area of cubes.
