How many faces does a hexahedron have?

A hexahedron is a three-dimensional geometric shape that has six faces. The term "hexahedron" is derived from the Greek word "hex," meaning six. This shape is often associated with a cube, which is a specific type of hexahedron where all faces are squares. However, any polyhedron that has six flat faces qualifies as a hexahedron.

To visualize this, consider that each face of a hexahedron can be a polygon, and when you compile six of these faces together in space, they form a closed three-dimensional figure. Thus, regardless of the shape of the individual faces, as long as there are six, the figure is classified as a hexahedron.

This aligns with the options provided, confirming that the correct answer is indeed that a hexahedron has six faces.
