Hence a cylinder is a little more than 3 (.78+) of its circumscribed square right prism.

Note 13. If from a cylinder of wood whose diameter equals its altitude the largest possible sphere be cut, exactly of the wood will be cut away. Hence a sphere is exactly of a cylinder whose diameter and altitude are each equal to the diameter of the sphere.

Note 14. If from a cylinder of wood the largest possible cone be cut, exactly of the wood will be cut away. Hence a cone is exactly of a cylinder of equal diameter and altitude.

Note 15. If from a square right prism of wood the largest possible pyramid be cut, exactly of the wood will be cut away. Hence a square pyramid is exactly of a square right prism of equal base and altitude.

Note 16. The specific gravity of a liquid or solid is the ratio of its weight to the weight of an equal bulk of pure water.
