Volume Calculations and Composite Figures

Mrs. Cox's math lesson covers chapter 12, lesson 11, focusing on calculating the volume of composite figures. The lesson includes examples with prisms, using both whole numbers and decimals. Students are guided through various examples, including a cake and a building remodel, to understand volume calculation. The session concludes with drawing exercises and assignments for further practice.

Why is it important to complete the guided practice before starting the lesson?

• It is mandatory for attendance.

• It is not necessary.

• It helps in understanding the lesson faster.

• It provides extra credit.

What is a composite figure?

• A two-dimensional shape.

• A single three-dimensional shape.

• A figure made up of two or more three-dimensional shapes.

• A figure with no volume.

How do you calculate the volume of a rectangular prism?
