The thirteenth and last book of the Elements of Euclid deals with the construction of the five "Platonic solids": the tetrahedron, octahedron, cube, icosahedron and dodecahedron. It applies Eudoxus' method of exhaustion to prove that the areas of circles are to one another as the squares of their diameters and that the volumes of spheres are to one another as the cubes of their diameters. It includes the construction of the five regular Platonic solids (pyramid, cube, octahedron, dodecahedron, icosahedron) inside a sphere.

The thirteenth book of "Euclid's Elements" is called regular solids. In this final book, Euclid names and describes the properties of the five regular solids and ends it by proving no other regular solids exist.

The thirteenth book in Euclids Elements has no specific title, but covers the Pythagorean proofs of Theaetetus (c. 417-369 bc) and the construction of the five regular Platonic solids (pyramid, cube, octahedron, dodecahedron, icosahedron) inside a given sphere.

Euclid's accomplishments had to do with geometry. His greatest accomplishment was his book on geometry called Elements. In this book, he mentions conic sections, number theory and more. He is also responsible for Euclidean geometry.
