### Solid Shapes

Geometry is one of the experimental sections of Mathematics that includes figures of different shapes and sizes having distinct properties. Generally, Geometry deals with two types of shapes- solid shapes and plane shapes. We have observed that the plane picture that is drawn on paper does not occupy any space whereas if we draw a real picture on a paper it occupies some space. Hence, such real shapes that occupy some space are known as solid shapes or three -dimensional shapes.

### What are Solid shapes in Geometry?

In Geometry, the three - dimensional objects having depth, width, and height are known as solid shapes. For example, a circle drawn on a piece of paper is a two-dimensional figure whereas a ball in the shape of a sphere is a three-dimensional figure. Let us learn some of the solid shapes below.

### Properties of Three-Dimensional or Solid Shapes

Some of the properties of three-dimensional or solid shapes are given below:

Faces - A face is a curve or flat surface on the three-dimensional shapes.

Edge - An edge is a line segment formed between the faces.

Vertex - A vertex is a point where the two edges of three-dimensional shapes meet each other.

### Types of Solid Shapes

### Cube

A cube is a three-dimensional or solid shape having 6 square faces. The following are the properties of the cube.

All edges of cube are equal

8 Vertices

12 Edges

6 Faces

### Cuboid

A cuboid is a solid shape formed by two-dimensional rectangular faces also known as rectangular prisms. Some of the properties of Cuboid are:

8 Vertices

12 Edges

6 Faces

The measurement of all the angles of a cuboid are 90⁰,

Opposite faces and edges of a cuboid are equal.

### Prism

A prism is a three-dimensional shape that includes two equal ends, flat faces or surfaces, and have similar cross-sections across its length. The prism is also known as a triangular prism as the cross-section of a prism looks like a triangle. The prism does not have any curve. The following are the properties of prisms.

9 Edges

6 Vertices

5 Faces ( 2 triangles and 3 rectangles)

### Cone

A cone is a three-dimensional or solid object which has a circular base and has a single vertex. The cone is a geometric figure that minimizes smoothly from the circular flat base to the top point known as apex. A cone has

1 Vertex

1 Edge

1 Flat face- circle

1 Curved face

### Cylinder

A cylinder is a three-dimensional geometrical figure that has two parallel bases joined by the curved surfaces. The cylinder has

3 Faces

2 Edges

0 Vertices

### What is the Net of Solid Shapes?

A two-dimensional geometric figure that can be folded to form a three-dimensional solid shape is referred to as a geometry net. When the surface of the three-dimensional figure is arranged in a flat position showing each face of the figure, the pattern obtained is known as the net of the solid shape. Solid shapes may be different. In other words, the net is an unfolded form of a three-dimensional figure.
