Solid Figures

What do you know about a Solid Figure?

Mathematicians study shapes and all of their varieties and work to apply them to everyday situations. Any solid form that has the three dimensions of length, breadth, and height is considered to be a solid shape. The classifications of solid shapes are diverse. Some are shaped like pyramids or prisms, while others have curved surfaces. Now, let's examine each solid shape in more detail.

What is a Solid Figure

A solid figure is one that we can feel by using our hands. Three-dimensional things are represented by solid forms. Take a look around! Every other three-dimensional item, such as a laptop, telephone, ice cream cone, balls, and so on, is an example of a solid form. These take up some room and have length, breadth, and height. Let's look at the features and pictures of solid figures and understand their properties.

Solid Figures Examples

There are many solid shapes (3D shapes) with different bases, volumes, and surface areas. Let's discuss each of them.

1. Sphere

The sphere is rounded in shape. This is a three-dimensional geometry in which all points on the surface are equidistant from the centre. It has a radius, diameter, circumference, volume, and surface area. It is a perfectly symmetrical figure with no edges and is shaped like a ball.

2. Cube and Cuboid

Cubes and cuboids are three-dimensional shapes  with the same number of faces(6), vertices(8), and edges(12). The main difference between a cube and a cuboid is that a cube has all six faces square and a cuboid has all six faces as a rectangle. Cubes and cuboids have different volumes and different surface areas. The length, width, and height of a cube are the same, but the length, height, and width of a cuboid are different.

3. Cylinder

A cylinder is a three-dimensional shape with two round faces (one at the top and one at the bottom) and one curved surface. The bases are always parallel to one another and are either oval or circular in shape. A cylinder has a height and a radius. The height of a cylinder is the vertical distance between its top and bottom faces. It has one curved edge. The shape remains the same from bottom to top.

4. Cone 

A cone is another three-dimensional shape (3D shape) with a flat bottom (round shape) and a pointed tip on the top. Its shape is similar to a rotated triangle. The sharp end of the top of the cone is called the "top". A cone also has a curved surface. A cone has a height and a radius. In addition to height, cones have an oblique height, which is the distance between a vertex and a point on the perimeter of the cone's circular base.

Conclusion

Solids, or three-dimensional things, are composed of length, width, and height. Faces, edges, and vertices are all characteristics of solid forms. Learning about solid forms can benefit us in our daily lives because they are used in so many of our activities and their area can be calculated giving us an idea about how much space they will occupy in any place.
