Class 6 Maths Chapter 5 Exercise 5.8 Explanation

#### Solid

An object that has a fixed shape and size is called a solid. A solid occupies a fixed amount of space. Solids occur in different shapes.
These shapes are known as three-dimensional shapes.

##### Cuboid Solids such as a matchbox, a book, a brick, a wooden box etc.
are all in the shape of a cuboid? A cuboid has length, breadth and height.
A cuboid has 6 rectangular surfaces, called its faces. The opposite faces of a cuboid are identical. Two adjacent faces of a cuboid meet in a line segment called edge of the cuboid. A cuboid has 12 edges. It has 8 vertices.

##### Cube A cuboid having all edges of same length is called a cube. Dice,
ice cubes, sugar cubes etc. are all examples of a cube.
A cube has 12 edges, 8 vertices and 6 faces. Each face of a cube is a square.

##### Cylinder A cylinder has 3 faces, 2 plane faces and 1 curved face.
It has 2 edges and no vertex. The base and the top of a cylinder are identical.
A test tube, a gas cylinder, a circular pipe, a measuring jar etc. are all examples of a cylinder.

##### Sphere A sphere has 1 curved face. It has no vertex and no edge.
Football and cricket ball are examples of a sphere.

### What is solid?

An object that has a fixed shape and size is called a solid. A solid occupies a fixed amount of space. Solids occur in different shapes.

### What is cube?

A cuboid having all edges of same length is called a cube. Dice, ice cubes, sugar cubes etc. are all examples of a cube.

### Does a cone have a vertex?

Lead students to see that a cone has no edges, but the point where the surface of the cone ends is called the vertex of the cone. Students should realize that although a cylinder has two faces, the faces don’t meet, so there are no edges or vertices.

##### Cone A cone has 1plane face, which is its base. It has only 1 vertex.
A cone has only a single edge which is circular.
An ice-cream cone, a conical tent, a conical vessel etc. are in the shape of a cone.

### How many vertices do a cuboid have?

A cuboid has 8 vertices.

### How many faces do a cylinder have?

A cylinder has 3 faces, 2 plane faces and 1 curved face.

(i) Cuboid
(ii) Cylinder
(iii) Cone
(iv) Cylinder
(v) Sphere
(vi) Cube

### What is the difference between a cylinder and a cone?

A cone is a 3-dimensional solid object that has a circular base and a single vertex. Cylinder: A cylinder is a 3-dimensional solid object that has two parallel circular base connected by a curved surface.
