small bathrooms. i have kind of a similar fear, but I'm really only scared of small bathrooms, or monochromatic ones or ones with labels and directions as to what to do (like airplane or cruise ship bathrooms) I hate flying because of my fear, and always avoid airplane bathrooms.
A rectangular prism is solid 3-dimensional object which has six  faces that are rectangles. It has 12 edges and 8 vertices.
Best Answer: Octagonal prism. 10 faces = 8 sides + top + bottom. 24 edges = 8 vertical + 8 round top + 8 round bottom. 16 vertices = 8 on top + 8 on bottom. Hexagonal prism. 8 faces = 6 sides + top + bottom. 18 edges = 6 vertical + 6 round top + 6 round bottom. 12 vertices = 6 on top + 6 on bottom.
