the kind of space we live in
A solid with flat faces (from Greek poly- meaning "many" and -edron meaning "face")
A solid with curved side or a mix of curved and flat sides.
a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
a monumental structure with a square or triangular base and sloping sides that meet in a point at the top, esp. one built of stone as a royal tomb in ancient Egypt.
Cylinder a solid geometric figure with straight parallel sides and a circular or oval section.
Sphere a round solid figure, or its surface, with every point on its surface equidistant from its center.
Torus a surface or solid formed by rotating a closed curve, esp. a circle, around a line that lies in the same plane but does not intersect it (e.g., like a ring-shaped doughnut).
