Tetrahedron volume
Volume
From ancient times, people needed to measure the amount of various substances. Bulk substances and liquids could be measured by filling them with vessels of a certain capacity, determining their quantity by volume. The concept of volume in solid geometry is introduced similarly to the concept of area in plane geometry. In plane geometry, we determined the area like this: the area of a polygon is the value of the part of the plane that the polygon occupies. To formulate the concept of volume similarly to this concept. The magnitude of the part of the space occupied by the geometric body is called the volume of this body. Volume is measured in "cubic" units.
Tetrahedron
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.
Tetrahedron volume
The volume of the tetrahedron is equal to the fraction in the numerator product of square root two and the cube of the edge, and the denominator is twelve.
