The document describes two geometric solids and provides their edge, vertex, and face counts. For the first solid, it states it has 12 edges, 8 vertices, and 6 faces. For the second solid, it gives its counts as 15 edges, 10 vertices, and 7 faces. It then asks how many of each (edges, vertices, faces) are in the combination of the two solids, providing the solution that there are 18 edges, 12 vertices, and 8 faces total.
