Pyramids are three-dimensional tetrahedrons with a base, which can be rectangular or triangular, and corresponding sides comprised of triangles that meet at a single apex. Thus, because there are multiple kinds of pyramids, there are multiple pyramid-shaped or pyramid-like objects in and around the household.
The biggest pyramid in some houses is the roof of the house. Around the kitchen, there are objects like cheese graters and blocks of cheese or an arranged stack of fruits like apples or oranges that can be pyramid in shape. Pyramids can be built with toy building blocks, like Legos, or arranged delicately with a deck of cards. There are also pyramid-shaped paperweights for home offices as well as pyramid-shaped perfume bottles. For the outdoors side, there are pyramid-shaped deck umbrellas and tents. Common visuals of pyramids that can also be around the house are books, posters or souvenirs related to the famous Egyptian Pyramids, as well depictions of the Food Pyramid, which diagrams the healthy total suggested food intake of individuals. On the back of the American dollar bill is the famous "Eye of Providence," the symbol of the pyramid with an eye. Some candy bars, like the Toblerone chocolate bar, also are pyramidal in structure.
