Well, darling, common objects that come in a prism shape include pyramids, certain crystal decorations, and even some fancy perfume bottles. Just remember, a prism is a three-dimensional figure with a polygon as its base and triangular faces that meet at a common point. So, keep your eyes peeled for those sharp corners and dazzling reflections!
No, a square-based pyramid is not a prism. A prism is a polyhedron with two parallel and congruent faces called bases, and all other faces are parallelograms. In contrast, a square-based pyramid has a square base and triangular faces that meet at a single point called the apex. Therefore, a square-based pyramid does not meet the definition of a prism.
