Tetrahedron area calculator

Area is a numerical characteristic of a two-dimensional (flat or curved) geometric figure, informally speaking, showing the size of this figure. Historically, the calculation of the area was called quadrature. A figure having an area is called quadratic. Find the area of more than 22 shapes (triangle, square, pentagon, etc.) using our amazing calculator.

Tetrahedron — is a polyhedron whose faces are four triangles. The tetrahedron has four faces, four vertices, and six edges. One of the triangles is called the base of the tetrahedron, and the other three are called the lateral faces of the tetrahedron.

A tetrahedron is a geometric solid with four triangular faces. The area of a tetrahedron can be calculated using its edge lengths. The formula for finding the area of a tetrahedron is:

S = \sqrt{3}a^2

where A is the area of the tetrahedron and a is the length of its edges.

How to Use the Tetrahedron Area Calculator

Our tetrahedron area calculator makes it easy to find the area of your tetrahedron. To use the calculator just enter the length of the edge. Our calculator will automatically make all calculations and provide you with the answer.

Here's an example:

Example: In the example above, we have a tetrahedron with edges a - 6 lengths. So the area will be:

S = \sqrt{3}6^2= 62.3 cm^2

Tetrahedron Area Examples

Here are some examples of finding the area of a tetrahedron using the formula:

Example 1: Find the area of a tetrahedron with edges of length 8.

S = \sqrt{3}8^2= 110.85 cm^2

Example 2: Find the area of a tetrahedron with edges of length 3.

S = \sqrt{3}3^2= 15.58846 cm^2
