What is the term for a rectilinear parallelepiped?

I guess it could be called a cuboid, but the corresponding circular shape called a spheroid has the dimension in 2 of the axes as the same. Perhaps it is called rectoid or rectohedron?

I'm surprised you found PF but did not try parallelepiped

I'll just refer to the case of no repeated dimensions as cuboid, and with one repeated dimension as square cuboid, which can be of the two types prolate cuboid & oblate cuboid.

I'll just refer to the case of no repeated dimensions as rectangular cuboid, and with one repeated dimension as square cuboid, which can be of the two types prolate square cuboid & oblate square cuboid. It seems that a cuboid is any polyhedron that was originally a cube, but with any manner of applied stretch and/or shear.
