Step 1. We are given the names of 4 solids:
• triangular pyramid
,
• triangular prism
,
• rectangular prism
,
• square pyramid
And we need to find which one has 8 vertices.
Step 2. A vertex in a solid is a point where two or more lines meet.
In the following image, we can see an example of the four solids:
Step 3. Now that we have identified the four solids, we count the number of vertices on each of them. In the following image each red point represents a vertex:
The solid that has 8 vertices is the RECTANGULAR PRISM.
Answer: Rectangular prism
