Abstract

A tetrahedron is a pyramid with four sides that are equilateral triangles. It is one of the basic building blocks of an object. So it is widely used in engineering. Determining the volume of tetrahedra is very important. It helps us to determine the exact mass of an object. This is very important work in engineering design. In addition to the tetrahedral volume formulas, this article gives some more tetrahedral volume formulas and some applications of its in engineering.
