Visualizing Solid Shapes – Sample Problems
Question 1: How many vertices are there in a sphere?
Answer:
Sphere has no vertices in there because it has round shape.
Question 2: Is a cone polyhedron? Give explanation.
Answer:
Cone is not a polyhedron because it has round shape. Polyhedron is a 3D shape made by joining many polygons together. Polyhedron comes from Greek, poly means many and hadron means surfaces for example prism, cube, pyramid etc. are polyhedron 3D shapes.
Question 3: What is a triangular pyramid? What is a pyramid called if it has a square base?
Answer:
If a triangle has triangle shape of bottom then it is a triangle pyramid if a triangle has square shape of bottom then it will be called as a square pyramid its depend on bottom of pyramid.
Visualizing Solid Shapes
Visualizing Solid Shapes: Any plane or any shape has two measurements length and width, which is why it is called a two-dimensional(2D) object. Circles, squares, triangles, rectangles, trapeziums, etc. are 2-D shapes. If an object has length, width, and breadth then it is a three-dimensional object(3D). cube, pyramids, spheres, cylinders, and cuboids are 3-D shapes.
Any kind of solid shape occupies some space. A solid shape or figure is bounded by one or more surfaces. If any two faces of 3-D shapes meet together, we get a line segment which is called an edge when more than two faces of the solid meet at one point then that point is called the vertex of the solid.
In this article, we will study about visualizing solid shapes like cylinders, cubes, spheres, cones, etc, and their properties.
