The Empire State Building is composed of multiple shapes. The picture below should help.
It has a wider base but is essentially a set of rectangular prisms going up the building.
Toward the upper floors there are a pair of rectangular prisms with rounded corners. I suppose these might technically be octagonal prisms (8 sides), I'm not sure.
Then there is a set of levels that are square then a cylinder on top. The absolute tippy-top is a hemi-sphere (half sphere).
