1. **Problem Statement:** (a) Complete the table for a cube solid with uniform cross sections. Given: A cube has 12 edges and 8 vertices. We need to find the number of edges and vertices in 4 such solids. 2. **Formula and Rules:** - Number of edges in one cube = 12 - Number of vertices in one cube = 8 - For multiple solids, multiply by the number of solids. 3. **Calculations:** - Number of edges in 4 cubes = $4 \times 12 = 48$ - Number of vertices in 4 cubes = $4 \times 8 = 32$ 4. **Cross Section Drawing:** - A cross section of a cube parallel to its base is a square. **Final answers:** (a) Number of edges in 4 solids = 48 Number of vertices in 4 solids = 32 (b) Cross section is a square parallel to the base.
