Given, cuboid The surface where a solid object stands on is called the base of the solid. Base of a cuboid = Rectangle A face is any of the individual flat surfaces of a solid object. Number of faces of a cuboid = 6 Edges are the lines at which faces meet. Number of edges of a cuboid = 12 A vertex is the point at which when three or more edges meet. Number of vertices of a cuboid = 8 Given, a cube Base of a cube = Square Number of faces of a cube = 6 Number of edges of a cube = 12 Number of vertices of a cube = 8 A triangular prism: A triangular prism has 5 faces, 9 edges and 6 vertices. A quadrilateral prism: A quadrilateral prism has 6 faces, 12 edges and 8 vertices. A pentagonal prism: A pentagonal prism has 7 faces, 15 edges and 10 vertices. A hexagonal prism: A hexagonal prism has 8 faces, 18 edges and 12 vertices. A triangular pyramid: A triangular pyramid has 4 faces, 6 edges and 4 vertices. A quadrilateral pyramid: A quadrilateral pyramid has 5 faces, 8 edges and 5 vertices. A pentagonal pyramid: A pentagonal pyramid has 6 faces, 10 edges and 6 vertices. A hexagonal pyramid: A hexagonal pyramid has 7 faces, 12 edges and 7 vertices.
