How many reflection symmetries does every right prism have i

How many reflection symmetries does every right prism have if its bases are rectangles that are not squares?

If a figure is a right prism it has as many reflection
symmetric planes as the base has SYMMETRY lines
plus one additional one parallel to the
BASES.
So, a rectangle has 2 symmetry lines + 1 along the base.
So, 3 reflection symmetry
