Top
Its a pentagonal prism.
A right circular cone could probably do that.
The shape is 3 dimensional, the top down view is 2 dimensional.
the shape of a dome volcano is like an triangle
A square.
Front view = elevation, top view = plan and side view = end elevation
It depends on the shape. The top of a pyramid will be a point (the apex). The top (and bottom) of a prism or an antiprism will be congruent polygons.
Any face that is not a base of a solid is called a lateral face. In three-dimensional geometry, lateral faces connect the edges of the base and contribute to the overall shape of the solid. For example, in a prism, the lateral faces are the sides that are not the top or bottom bases.
The given net shows a hexagonal prism, which is a three-dimensional shape with two hexagonal faces and six rectangular faces connecting them. The hexagonal faces are the bases of the prism, while the rectangular faces are the lateral faces. When the net is folded along the edges and assembled, it forms a hexagonal prism with a regular hexagon as its base and top.
A three-dimensional shape with one circular base connected by a curved side to a single vertex is called a cone. The base is a circle, and the curved side extends from the edge of the base to the apex, or vertex, at the top. Cones can be found in various applications, such as ice cream cones or traffic cones.
Three dimensional printers and computing
The top of a cube is referred to as the "top face" or "upper face." In a three-dimensional context, a cube has six faces, and the top face is one of them, opposite the bottom face. Each face of the cube is a square.
