A rectangular prism does not have 4 edges. In fact, a rectangular prism has 12 edges. But let’s break it down to understand why.

First, let’s clarify what a rectangular prism is. A rectangular prism is a three-dimensional shape that has six rectangular faces, where each face is a rectangle. It is also known as a rectangular cuboid or a rectangular parallelepiped.

To count the number of edges, we need to understand what an edge is. An edge is the line segment where two faces of a solid meet. In the case of a rectangular prism, each edge is formed by the intersection of two adjacent faces.

Now, let’s visualize a rectangular prism. Imagine a shoebox or a rectangular gift box. It has six faces, with each face having four edges. So, we have a total of 6 faces x 4 edges per face = 24 edges.

However, we need to remember that each edge is shared by two faces. So, to find the total number of unique edges, we divide the total number of edges by 2. This gives us 24 edges / 2 = 12 unique edges.

To further illustrate this, let’s examine the image provided. In the image, the edges of the rectangular prism are labeled in green. By counting these green edges, we can confirm that there are indeed 12 edges.

Additionally, a rectangular prism has 8 vertices, which are the points where three edges meet. These vertices are labeled in red in the image. Counting the red vertices in the image, we can confirm that there are 8 vertices in a rectangular prism.

A rectangular prism has 12 edges and 8 vertices. The green edges in the image represent the 12 edges of a rectangular prism, while the red vertices represent the 8 vertices.
