It is formed by revolving a smaller circle of radius (r) around a larger circle with a bigger radius (R) in a three-dimensional space. Apart from the height, a cone has a slant height, which is the distance between the apex and any point on the circumference of the circular base of the cone.Ī torus is a 3D shape.

A cone in which the apex lies anywhere away from the center of the base is called an oblique cone. A cone in which the apex (or the pointed tip) is perpendicular to the base is called a right circular cone.Based on how the apex is aligned to the center of the base, a right cone or an oblique cone is formed.A cone has a circular or oval base with an apex (vertex).Similar to a cylinder, a cone can also be classified as a right circular cone and an oblique cone. The pointed end at the top of the cone is called 'Apex'. A cylinder in which one base is placed away from another is called an oblique cylinder.Ī cone is another three-dimensional shape (3D shape) that has a flat base (which is of circular shape) and a pointed tip at the top. A cylinder in which both the circular bases lie on the same line is called a right cylinder.It is a three-dimensional object with two identical ends that are either circular or oval.The shape stays the same from the base to the top.Some important features of a cylinder are listed below. The height of a cylinder is the perpendicular distance between the top and bottom faces. CylinderĪ cylinder is a 3D shape that has two circular faces, one at the top and one at the bottom, and one curved surface. The length, width, and height of a cube are the same, while for a cuboid, length, height, and width are different. A cube and a cuboid occupy different volumes and have different surface areas. The main difference between a cube and a cuboid is that in a cube, all its six faces are squares and in a cuboid, all its six faces are rectangles. It is not a polyhedron since it does not have flat faces.Ĭube and cuboid are three-dimensional shapes (3D shapes) that have the same number of faces, vertices, and edges.It has one face, no edges, and no vertices.Every point on the sphere is at an equal distance from the center.It has a radius, diameter, circumference, volume, and surface area.It is shaped like a ball and is perfectly symmetrical.Some important characteristics of a sphere are as follows. A spheroid resembles a sphere but the radius of a spheroid from the center to the surface is not the same at all points. Our planet Earth resembles a sphere, but it is not a sphere. It is a 3D geometric shape that has all the points on its surface that are equidistant from its center. There are many 3 dimensional shapes (3D shapes) that have different bases, volumes, and surface areas.
