A solid figure contained by six parallelogram faces, the central geometric object of Book XI propositions on solid geometry, whose equality, proportionality, and construction are repeatedly proved.
If a parallelepipedal solid be cut by a plane which is parallel to the opposite planes, then, as the base is to the base, so will the solid be to the solid.
If three straight lines be proportional, the parallelepipedal solid formed out of the three is equal to the parallelepipedal solid on the mean which is equilateral, but equiangular with the aforesaid solid.
Let the parallelepipedal solids AE, CF, of the same height, be on equal bases AB, CD.
