1. Problem Description
The problem asks to find the number of edges of the given 3D shape, which appears to be a square pyramid.
2. Solution Steps
We need to count the edges of the shape in the image.
The base of the pyramid is a square, which has 4 edges.
The pyramid has 4 triangular faces. Each of these triangular faces contributes one edge that connects the apex of the pyramid to one of the vertices of the square base. Therefore, there are 4 such edges.
The total number of edges is the sum of the edges on the base and the edges connecting the apex to the base.
Total edges = 4 (base) + 4 (connecting apex to base) =
