Go Math Grade 5 Chapter 9 Lesson 92 Answer Key: Tips And Review

Introduction

As a fifth-grader, you might find math challenging, especially when it comes to complex topics such as fractions, decimals, and geometry. However, with the right resources and guidance, you can excel in math and achieve your academic goals. Go Math is a comprehensive math program that can help you improve your math skills and prepare for middle school. In this article, we will review Chapter 9 Lesson 92 of Go Math Grade 5 and provide you with some tips to solve the problems and understand the concepts.

Overview of Go Math Grade 5 Chapter 9

Chapter 9 of Go Math Grade 5 focuses on geometry and measurement. The chapter covers topics such as perimeter, area, volume, and surface area of 2D and 3D shapes. Lesson 92 specifically deals with finding the surface area of rectangular prisms and cubes. The lesson introduces the concept of nets and explains how to use them to find the surface area of a 3D shape.

Understanding Surface Area

Before we dive into the lesson, let\’s review the concept of surface area. Surface area is the total area of all the faces or surfaces of a 3D shape. For example, if we have a rectangular prism with length, width, and height of 3, 4, and 5 units, respectively, the surface area would be: – The area of the top and bottom faces: 3 x 4 = 12 square units each – The area of the front and back faces: 3 x 5 = 15 square units each – The area of the left and right faces: 4 x 5 = 20 square units each The total surface area would be the sum of all these areas, which is 12 + 12 + 15 + 15 + 20 + 20 = 94 square units.

Using Nets to Find Surface Area

A net is a 2D representation of a 3D shape that can be folded to form the shape. In Lesson 92, you will learn how to use nets to find the surface area of rectangular prisms and cubes. The lesson provides step-by-step instructions and examples to help you understand the process.

Tips to Solve the Problems

Here are some tips to help you solve the problems in Lesson 92: – Draw the net of the shape and label the faces with their dimensions. – Calculate the area of each face using the appropriate formula (e.g., length x width for rectangles). – Add up the areas of all the faces to find the total surface area. It\’s important to double-check your work and make sure you have included all the faces in your calculation.

Conclusion

Go Math Grade 5 Chapter 9 Lesson 92 is a crucial lesson that can help you understand the concept of surface area and how to find it using nets. By following the tips and examples provided in the lesson, you can improve your math skills and prepare for more advanced topics in middle school. Remember to practice regularly and seek help from your teacher or tutor if you need further assistance. Good luck!
