FAQs on RS Aggarwal Class 7 Solutions Chapter-19 Three-Dimensional Shapes
1. What are Faces, Vertices and Edges of 3D Shapes?
Every three-dimensional shape has three types of attributes which are present in every 3D object. These attributes are faces, vertices and edges. Faces are the flat surfaces present in the 3D shape. Edge is the point where two line segments meet. The point where three edges meet is known as a vertice.
2. What is a Cube?
A three-dimensional figure with 6 square faces is considered as a cube. All the sides of a cube are equal. A cube has 8 vertices, 12 edges and six faces. The face of the cube can also be considered as a regular polygon because all of its sides and angles are equal.
3. What is a Cuboid?
A three-dimensional shape whose faces are rectangular is known as a cuboid. A cuboid is also known as a rectangular prism. In a cuboid, all the angles equal to 90 degrees. A cuboid has 8 vertices, 12 edges and 6 rectangular faces. This face of the 3D shape is not considered as a regular polygon because the sides and angles of the face are not equal to each other.

5. What is a Pyramid?
A pyramid is a three-dimensional structure with a foundation made up of a polygon. You've probably heard of the Great Pyramid of Giza, which is built in the same way. This construction has a particular shape since each corner is connected to a single apex. A pyramid is made up of a polygonal base and flat triangle faces that meet at the apex. The bases are connected to the peak to form a pyramid. Each of the base's edges is connected to the apex, forming a triangle face known as the lateral face.
