## Surface Area of a Tetrahedron – Formula and Examples

A tetrahedron is a regular pyramid that is made up of four triangular faces. We can calculate the surface area of a tetrahedron by adding the areas of all four faces. In this article, we will explore the formula for calculating the surface area of a tetrahedron. We...

## Volume of a Tetrahedron – Formula and Examples

A tetrahedron is a regular pyramid. This means that we can calculate its volume by multiplying the area of its base by the height of the tetrahedron and dividing by three. In this article, we will learn about the formula to find the volume of a tetrahedron. We will...

## Height of a Tetrahedron – Formula and Examples

The regular tetrahedron is one of the five Platonic solids. We can think of a tetrahedron as a regular triangular pyramid. Its height can be calculated using a formula derived using the Pythagorean theorem. Here, we will learn about the formula for the height of a...

## Elements of the Platonic Solids

The most important elements of the Platonic solids are the faces, the vertices and the edges. In addition, we also have additional secondary elements such as lines of symmetry and cross-sections. In this article, we will take a look at the five Platonic solids and we...

## The 5 Platonic Solids – Properties, Diagrams and Examples

Platonic solids are three-dimensional figures, in which all their faces are congruent regular polygons. In total, there are five Platonic solids: tetrahedron, cube, octahedron, dodecahedron, and icosahedron. These figures are associated with the five elements of...
