this deals with a rectangular prism:
RECTANGULAR PRISM HAS (6 FACES)
4 FACES ARE FORMED BY RECTANGLES
2 FACES ARE FORMED BY SQUARES
A RECTANGULAR PRISM HAS 12 EDGES
A RECTANGULAR PRISM HAS 8 VERTICES
t FOR TRUE, f FOR FALSE
T : IT HAS NO CURVED SURFACES
T: ALL OF THE EDGE ARE PARALLEL
T: ALL THE FACES ARE POLYGON
f: ALL THE FACES ARE CONGRUENT
BUT MY TEACHER SAID THERE ARE 2 F AND 2 T

Are ALL edges parallel?
