o the baseNP; for the solids AB, CV are of the same altitude; and as thesolid CD to CV, so (25. 11.) is the base MP to the base PT, andso (1. 6.) is the straight line MC to CT; and CT is equal to AG.Therefore, as the base EH to the base NP, so is MC to AG.Wherefore, the bases of the solid… … the base NP, so the altitude of the solid CD to the alti-tude of the solid AB; the solid AB is equal to the solid CD. Let the insisting lines be, as before, at right angles to the bases. Then, if the base EH be equal to the base NP, since EH is to NP, as A E C N the altitude of the solid CD is to…
