Spheres
Three shapes that have faces with perpendicular edges are the cube, rectangular prism, and the right rectangular prism. In these shapes, the faces intersect at right angles, creating edges that are perpendicular to one another. This characteristic is a defining feature of their geometric structure, allowing for the formation of right angles throughout the shape.
Cubes and rectangular prisms are examples of 3D shapes that have both parallel and perpendicular edges. In a cube, each edge is parallel to another edge on the same face and perpendicular to edges on adjacent faces. Similarly, a rectangular prism has edges that run parallel along its length, width, and height, while the edges connecting different faces are perpendicular to each other. Other shapes, like some types of polyhedra, can also exhibit this property.
In a heptagonal prism, there are 7 rectangular lateral faces along with 2 heptagonal bases. The rectangular faces have edges that are perpendicular to the edges of the heptagonal bases. Therefore, there are 7 faces with perpendicular edges in a heptagonal prism.
There is no such shape as a perpendicular prism.

Any shape with straight edges can have perpendicular edges.
In a heptagonal prism, there are 7 rectangular lateral faces along with 2 heptagonal bases. The rectangular faces have edges that are perpendicular to the edges of the heptagonal bases. Therefore, there are 7 faces with perpendicular edges in a heptagonal prism.
A cuboid
Assuming a regular decagon is the base of the prism, it would be 10 faces. With an irregular decagon, it is possible that two (or more) of the edges of the decagons are perpendicular, so all 12 faces could have perpendicular edges.
It doesnt matter -.- GET A LIFE !
circle, sphere and another shape do not have faces or edges
Hexagonal prism has percandicular faces
There is no such shape as a perpendicular prism.
An heptagonal based prism, also known as a heptagonal prism, has two faces that are perpendicular to each other. These faces are the bases of the prism, which are heptagons in this case. The perpendicular edges are the edges that connect the vertices of the bases at right angles, resulting in a total of 14 perpendicular edges in a heptagonal prism.
