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.
