Understanding Shapes Without Curved Surfaces
In geometry, shapes can be classified based on their surfaces. Some shapes have curved surfaces, while others have flat surfaces. Let’s explore the options given in the question.
Shapes with Curved Surfaces
- Sphere: A sphere is perfectly round and has no edges or vertices. It is entirely curved, like a basketball or a globe.
- Cylinder: A cylinder has two flat circular bases and a curved surface connecting them. Think of a soda can, which has a circular top and bottom with a curved side.
- Cone: A cone has a flat circular base and a pointed apex. The side of the cone is curved, similar to an ice cream cone.
Shape Without Curved Surfaces
- Cube: A cube is a three-dimensional shape with six flat square faces. Each face meets at right angles, and there are no curves involved. Examples of cubes include dice and building blocks.
Conclusion
Among the options provided, the cube is the only shape that has no curved surfaces. It consists entirely of flat surfaces, making it distinct from the sphere, cylinder, and cone, all of which have curves. Thus, the correct answer is option 'D' (Cube).
