Given a cube, its midpoint cube is obtained by joining the midpoints of its faces. A sequence of polyhedra $Q_{i}$ is defined recursively as follows: $Q_{0}$ is a regular cube whose volume is 1. To obtain $Q_{i + 1}$, replace the midpoint square of every face of $Q_{i}$ by an outward-pointing regular square pyramid that has the midpoint square as a base. The volume of $Q_{3}$ is represented as $\frac {p}{q}$, where $p$ and $q$ are relatively prime positive integers. Find $p + q$.
