Three-dimensional shapes can be measured in three directions; these shapes are also known as solids. Three-dimensional shapes consist of three dimensions, which are height (or thickness or depth), width and length. The thickness in these shapes makes them different from two-dimensional shapes.
Class 6 Three Dimensional Figures - Edges, Vertices and Faces
There are three attributes in a three-dimensional figure - edges, vertices, and faces. The faces are the flat surface of a three-dimensional shape. Edges are the point where two faces meet and three edges together make a vertex. The naming of the three-dimensional shapes is as follows-
Cuboid - A rectangular prism whose faces are of rectangle shape is called a cuboid. All the angles of the cuboid are 90 degrees. A cuboid has 8 vertices, 12 edges, and 6 faces.
Cube - A solid shape that has 6 square faces is called a cube. A cube has 8 vertices, 12 edges, and 6 faces. All the edge lengths are equal in the cube.
Cylinder - A geometrical figure that has two circular faces joined by a curved surface is called a cylinder. A cylinder has no vertex, 2 edges, 3 faces (two flat faces and one curved face).
Cone - A geometrical figure that has a circular base and a single vertex is called a cone. A cone has one vertex, one edge, one flat face, and one curved face.
Sphere - A perfectly round in shape that has every point on its surface equidistant to the centre is called a sphere. A sphere has no vertex, no edges, one curved face.
Prism - A three-dimensional figure that has two equal ends, and a flat surface, also has an identical cross-section across its length is called a prism. A prism has six vertices, nine edges, and five faces.
Pyramid - A solid shaped figure that has triangular faces and meets at a point on its top is called a pyramid. The base of the pyramid can be of any shape like a square, triangle, or quadrilateral. The number of E, V, F depends on the base shape.
