Abstract
An integration formula of the type
referred to as a product quadrature, was first considered by R. Boland and C. Duris. In this paper, the author extends the concept of a product formula to multiple integrals. The definitions and some of the results for interpolatory, compound, and symmetric product quadratures have an analog for product cubatures and these are given.
