The different types of prisms are triangular prisms, square prisms, pentagonal prisms, hexagonal prisms, etc. Based on their apex alignment with the center of the base, they can be classified into regular and oblique pyramids.Ī prism is a solid shape defined on a 3-dimensional plane with two identical shapes facing each other.A pyramid is a polyhedron with a polygon base and an apex with straight lines.The table below shows the properties of a pyramid: (BA = base area, P = perimeter, A = altitude, and SH = slant height ) Properties Regular hexagon base is called a hexagonal pyramid.Pentagon base is called a pentagonal pyramid.A quadrilateral base is called a square pyramid.Triangular base is called a Tetrahedron.Pyramids are typically described by the shape of their bases. It has a circular or oval base with an apex (vertex).Ī pyramid is a solid shape or a polyhedron with a polygon base and all lateral faces are triangles.The table below shows the properties of a cone where r denotes radius, h represents height and s represents slant height of the cone: Properties Based on how the apex is aligned to the center of the base, a right cone or an oblique cone is formed. It is formed by a set of line segments connected from the circular base to a common point, known as the apex or vertex. It has a flat surface and a curved surface, pointing towards the top. It is a three-dimensional object with two identical ends that are either circular or oval.Ī cone is a distinctive solid shape defined in a three-dimensional space.The bases are always congruent and parallel.The table below shows the properties of a cylinder: Properties It holds two parallel bases, circular in shape, joined by a curved surface(like a tube), at a fixed distance.
All points on the surface are the same distance (r) from the center.Ī cylinder is a solid shape defined on a three-dimensional plane.It is shaped like a ball and is perfectly symmetrical.The table below shows the properties of a sphere: Properties Every point on the surface is equidistant from the center. Let's explore types of solid shapes-Ī sphere is a solid shape, absolutely round in shape, defined in three-dimensional space. These occupy some space, have length, width as well as height. Look around! Every other three-dimensional object, be it a laptop, cellphone, an ice-cream cone, balls, etc, are examples of solid shapes. Solid shapes correspond to three-dimensional objects.
