How to read the X in 5X4間? A book about architecture I'm trying to read (it's a bit of a slog what with the technical jargon and such) contained this description of a temple building: X4 X3. So it's two stories, the first being five rooms by four, with lean-to rooms attached, etc. I have a few questions about this. First, how is the "X" in 5X4 read? Additionally, I'm assuming that and are read and , respectively. Is this correct?

The English "by" is read multiply in Japanese. A 3x4 matrix, for example, is 34 in Japanese. I assume your readings are right in the second part of your question, but can't seem to find them anywhere.
