An octagon.
A pyramid with a base that has seven sides.
Well if you have an 8 sided figure there is obviously 8 sides.
An eight-sided plane figure is an octagon. If the sides are all the same length, and the angles are all equal, it is a regular octagon.
It is an 8 sided octagon whose 8 interior angle add up to 1080 degrees and has 20 diagonals

An 8 sided octagon would fit the given description.
An Octagon
A two-dimensional figure is a polygon. The eight sides means that it uses the prefix octa- (meaning eight) to form the name octagon.
Because an "octagon" is defined as a closed plane figure with 8 vertices which is bounded by straight lines. It must, therefore, have eight sides.
