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.
Three dimensional printers and computing
For example, if you keep on stacking squares (two dimensional figure) on top of one another, it will slowly form a cuboid (three dimensional figures). There is a mathematical way of calling it. Google it!
A cylinder is a three-dimensional geometric shape, not a two-dimensional one. However, if we refer to its 2D representation, it can be visualized as a rectangle (representing the curved surface when unwrapped) and two circles (representing the top and bottom bases). In 2D, the essential characteristics of a cylinder are depicted through these shapes, highlighting its circular bases and height.
