rCise 6. does it have? b) How many edges (lateral edges plus base edges) does it have? C) How many faces (lateral faces plus bases) does it have? d At which point are the lateral edges concurrent? . Suppose that the lateral faces of the pyramid in Exercise 5 12 in, ABCE = 16 in, ACED 10 in?. If each side of the square base measures have AABE = 12 in, and %3D AADE 4 in., find the total surface area of the pyramid. %3D 0. Suppose that the base of the hexagonal pyramid in Exercise 6 has an area of 41.6 cm and that each lateral face has an area of 20 cm. Find the total (surface) area of the pyramid. 1. Suppose that the base of the square pyramid in Exercise 5 has an area of 16 cm and that the altitude of the pyramid measures 6 cm. Find the volume of the square pyramid. 2. Suppose that the base of the hexagonal pyramid in Exercise 6 has an area of 41.6 cm and that the altitude of the pyramid measures 3.7 cm. Find the volume of the hexagonal pyramid. . Assume that the number of sides in the base of a pyramid is n.
