Bótes i barrils Authors Armengol Gasull i Embid Abstract In this paper we consider the validity of several practical formulas used to calculate the volume of wine or cider barrels. In our study we will find, for instance, Simpsons formula for calculating definite integrals; a book written by Kepler on the subject; and the method of least squares established by Gauss and Legendre, for calculating the best solution for overdetermined and incompatible systems.
