3D Shape Names - an introduction

What is a Prism?
[size=150][size=200]A prism is a solid geometric figure whose two ends are similar, equal, and parallel, and whose sides are parallelograms.[/size][/size]
Rectangular Prism
 A solid object which has six faces that are rectangles
RECTANGULAR PRISM
What other objects do you know of that are rectangular prisms?
Cube
A symmetrical three-dimensional shape, contained by six equal squares.
CUBE
What other objects do you know of that are cubes?
Tetrahedron
A solid having four plane triangular faces, also known as a triangular pyramid
TETRAHEDRON
What other objects do you know of that are tetrahedrons?
Cylinder
A solid geometrical figure with straight parallel sides and a circular or oval cross section.
CYLINDER
What other objects do you know of that are cylinders?
Cone
A solid or hollow object which tapers from a circular or roughly circular base to a point
CONE
What other objects do you know of that are cones?
Are these Prisms too?
Do a little research to see if the following names are real prisms too.
