A pyramid with a polygonal base has as many edges as the number of sides of its base plus the number of edges in the base. A 100-gon pyramid would have 100 edges on its base and an additional number of edges equal to the number of sides of the base, which is also 100. Therefore, a 100-gon pyramid would have 100 + 100 = 200 edges.
A pyramid with seven sides has 12 edges. A pyramid based on a seven-sided base has 14 edges.
A pyramid is a generic term, used to describe a three dimensional shape with a polygonal base and triangular sides that meet at an apex above the base. The base can be a polygon with any number of sides and the number of faces, edges and vertices of a pyramid depend on this number of sides. If the base is an n-sided polygon, then the pyramid has 2n edges.
Five: four sloping triangular sides and a square base. It has eight edges.
8 four for the base and four for the sides going up the pyramid.
divide it by how many sides it has
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
A pyramid, whose base is a polygon with n sides (n>2) has 2n edges. A pyramid, without any descriptive qualifiers, is a square pyramid and would have 8 edges.
4+4+4+4 4 sides are the bottom(Base) of the cube, 4 of the sides are the verticle edges of the cube, 4 more of the sides are the top of the cube/and the base of the trianglular pyramid, and the other 4 are the edges of the pyramid. Total number of edges is 16
How many what? If you mean sides of a square based pyramid 5
a pyramid has 5 sides
16 edges- the edges of the base, and the edges leading to the point of the pyramid.
