There can be no answer to this question. This is because there cannot be a face that is a rectangular pentagon. Rectangular means it has four straight sides while pentagon means it has five straight sides. It can have either 4 or 5 sides - NOT both!
You cannot have a rectangular perntagon. A rectangular shape cannot have eight sides. A pentagon cannot have eight sides. Consequently, this question cannot be answered.
A pentagonal prism
You can't have a rectangular pentagon. Perhaps you mean regular? In any case every pentagon has 5 sides ("penta" = "five")

If the pentagon is regular, then each side of it is 502m long. But ifit is rectangular, then all bets are off, since no such shape exists.
A pentagonal prism
It could have four if it is concave.
it is 3 obtuse angles. A pentagon has five obtuse internal angles in plan view. i.e. looking down on it from above. A pentagon has five obtuse internal angles in plan view. i.e. looking down on it from above.
It is a prism with a pentagonal cross-section
In 2-d a pentagon, in 3-d a rectangular pyramid.
the other faces on a pentagonal prism would be rectangular
