In this lesson, we will learn how to identify 3D shapes and their properties.

Q1:

Which of the following is a point in a 3D shape?

Q2:

Which of the following is a line in a 3D shape?

Q3:

The following cube is a 3D shape that has a number of faces 𝐹, a number of edges 𝐸, and a number of vertices 𝑉.

What is the rule that connects the number of faces, edges, and vertices together?

If this rule can be used to connect the number of faces, edges, and vertices of all 3D shapes, for a 3D shape that has 5 faces and 5 vertices, how many edges does it have?
