In 3D graphics rendering, computing the rate of change of RGB color values between the points of each triangle (vertices) so that the triangles can be filled with color properly in the ...

The other four faces are all triangles. The shapes with 8 vertices are the cube and the cuboid. The cube has 6 faces all the same, but the cuboid has different faces.

6 × 2 = 12. A hexagonal prism has 12 vertices. A pyramid has one more face than the number of sides of its base. A triangle-based pyramid has four faces. A square-based pyramid has five faces.
