UpStudy AI · Accepted Answer

A **triangular prism** is a three-dimensional shape with two triangular bases and three rectangular lateral faces. To determine the number of edges in a triangular prism, let's break it down:

1. **Edges of the Triangular Bases:**
   - Each triangular base has **3 edges**.
   - Since there are **2 triangular bases**, the total number of edges from the bases is:
     $$
     3 \, \text{edges/base} \times 2 \, \text{bases} = 6 \, \text{edges}
     $$

2. **Edges Connecting the Bases (Lateral Edges):**
   - These are the edges that connect corresponding vertices of the two triangular bases.
   - There are **3 lateral edges** connecting the bases.

3. **Total Number of Edges:**
   $$
   \text{Edges from bases} + \text{Lateral edges} = 6 + 3 = 9 \, \text{edges}
   $$

**Answer:** Jackie counts **9 edges** in a triangular prism.
Jackie counts 9 edges in a triangular prism.
