A square pyramid has a square base, and a hexagonal pyramid has a hexagonal base. The volume of a pyramid is always one-third the volume of the corresponding prism. That prism has 2 congruent bases and the same height as the pyramid. The lateral area of the pyramid is just the sum of the areas of the ...
