Is it true A hexahedron is a prism whose base is a square?

Answer 1

A hexahedron is a 3D shape with 6 faces. It CAN be a prism whose base is a square. But that is only one example. It can also be a prism whose base is any quadrilateral. It can also be something like a pentagonal pyramid (i.e. the base is a pentagon and the sides are made up of 5 triangles.)

Answer 2

It is not true. Although a hexahedron can be such a shape but there are many other shapes that a hexahedron can have.
