PJ participated in field day.

8-8 Solve Problems Involving Surface Area – We took a practice quiz on Lesson 8-8 Solve Problems Involving Surface Area.

8-8 Solve Problems Involving Surface Area – We found the surface area of two-dimensional composite shapes. Then we found the surface area of three-dimensional composite shapes. We discovered that the surface area of a composite figure is the sum of the areas of its surfaces. The surface area of a three-dimensional figure is the combined surface area of all the faces of the figure.

8-8 Solve Problems Involving Surface Area – We learned three functions for finding the surface area of a cone, sphere, and cylinder. Then we worked on solving word problems using these functions.
Assignment: Complete four problems for homework.

We learned the names of several 3-dimensional shapes and identified the shapes in various real-world objects.

8-7 Describe Cross Section – We learned to describe cross sections of right rectangular pyramids and prisms. Then we solved problems involving cross-sections. We learned that cross-sections are two-dimensional figures that are exposed when a 3-dimensional figure is sliced by a plane.
