About This Chapter
Finding Area, Perimeter, Surface Area & Volume - Chapter Summary
When you study this chapter, you'll watch short videos about how to find surface area, volume, perimeter and area that you can work through at your leisure. Topics covered include finding the surface area of a cube, the area of a triangle and the volume of a prism. Once you complete this resource, you should be able to:
- Calculate the area of triangles and rectangles
- Define the circumference and area of circles
- Explain how to find the surface area of a cube and a rectangular prism
- Understand the process to find the surface area of a cylinder and a pyramid
- Discuss nets of 2-D maps and 3-D figures
- Find the volume of prisms and pyramids
- Identify the methods used to find the volume of cones, spheres and cylinders
Work at your own pace and feel free to go back and watch any of the video lessons again as needed using the timeline. Each video is accompanied by a self-assessment quiz so you can check your knowledge before moving on. Help from one of our experts is just a couple of clicks away in the Dashboard if you need it.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Nets of 3-Dimensional Figures
After watching this video lesson, you will be able to deconstruct a 3-dimensional figure into its 2-dimensional net. Learn what kind of shape you will get after opening and flattening your 3-dimensional figure.
7. Nets & Surface Area: 2-D Maps of 3-D Figures
Surface area can be tricky, but nets offer a quick way to be sure that you've accounted for each face of a given object when calculating that object's surface area. When you are through, test your understanding with a short quiz.
8. 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.
9. 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.
10. Combined Figures: Perimeter, Area, and Volume
Watch this video lesson to learn how you can break up the shapes in a combined figure to easily find the perimeter, area, and volume of the whole figure.
