Cross-Sections of 3D Shapes

The video tutorial by Mr. We Game explores the concept of slicing three-dimensional figures to understand the shapes formed by their cross-sections. It covers slicing various 3D figures such as rectangular prisms, triangular prisms, cylinders, pyramids, and cones both horizontally and vertically. The tutorial emphasizes the resulting shapes and discusses potential applications in calculating area and volume of these shapes.

What is the main focus when slicing 3D figures?

• To change the color of the figures

• To determine the shape of the cross-section

• To find the volume of the figures

• To calculate the surface area
