FAQs on Textbook Solutions: Three Dimensional Shapes - Mathematics Class 6 (Maharashtra Board)

1. What are the different types of three-dimensional shapes?
Ans. Three-dimensional shapes can generally be classified into two main categories: polyhedra and non-polyhedra. Polyhedra are shapes with flat surfaces (faces) that are polygons, such as cubes, prisms, and pyramids. Non-polyhedra include shapes with curved surfaces, like spheres, cylinders, and cones. Each type has distinct properties and characteristics that differentiate them from one another.
2. How do you calculate the volume of common three-dimensional shapes?
Ans. The volume of three-dimensional shapes can be calculated using specific formulas. For example, the volume of a cube is found by raising the side length to the power of three (V = side^3). For a rectangular prism, the formula is V = length × width × height. The volume of a cylinder is calculated using V = π × radius^2 × height, while for a sphere, the formula is V = (4/3) × π × radius^3. Each formula helps determine the space occupied by the shape.
3. What is the difference between surface area and volume in three-dimensional shapes?
Ans. Surface area refers to the total area of all the surfaces of a three-dimensional shape, while volume measures the amount of space inside the shape. For instance, a cube has a surface area calculated as 6 × side^2, whereas its volume is calculated as side^3. Understanding both concepts is crucial in various applications, such as packaging and construction.
4. Can you provide examples of real-life objects that represent three-dimensional shapes?
Ans. Yes, many everyday objects represent three-dimensional shapes. A basketball is an example of a sphere, while a can of soda represents a cylinder. A box is a common example of a rectangular prism, and a pyramid can be seen in structures like the Great Pyramid of Giza. Recognizing these shapes in the real world helps in understanding their properties and applications.
5. Why is it important to learn about three-dimensional shapes in mathematics?
Ans. Learning about three-dimensional shapes is essential because it enhances spatial awareness and geometric understanding. It has practical applications in fields such as architecture, engineering, and design. Additionally, it helps develop problem-solving skills and critical thinking, which are valuable in various academic and real-world scenarios.
