Abstract
Abstract A building structure is formed using four by eight foot plywood panels as raw material because of their ready availability. Hexagonal pyramids are formed by first cutting a panel diagonally to form two right triangles. These two right triangles are joined to form a triangular section having a height equal to its base. Six such sections are joined to form the hexagonal pyramids. Pentagonal pyramids are formed by cutting the panels using the eight foot lengths as the dimension of the hypotenuse. Each panel can produce two triangles and they are combined to form an equilateral triangular section. Five of these sections are combined to form each pentagonal pyramid. Reinforcement pyramids are joined in the interior of each pyramid. These are similar to the pyramids they reinforce, but of one half the size. The pyramids are combined using them as substitutes for the plane hexagonal and pentagonal surfaces of regular and semi-regular polyhedrons. These polyhedrons are simple in form and the use of the easily formed pyramids in producing the building structures requires no mathematics or sophisticated tools.
