Cubes, Prisms, Pyramids, Cylinders, Cones and Spheres Geometry - Solids Cubes, Prisms, Pyramids, Cylinders, Cones and Spheres

What is Solid Geometry? It is about three-dimensional space Geometric solids have a length, width AND height. There are Geometric solids all around us. Let’s Look Around!

Cubes All cubes have six square faces.

Prisms A prism has the same cross section all along its length. A cross section is the shape you get when cutting straight across the object. The cross section of this object is a triangle ... .. it has the same cross section all along its length ... ... and so it's a triangular prism.

Pyramids Do you think of Egypt when you hear pyramid? I do! Pyramids have an apex and a base. We name the pyramid by the shape of the base. Both pyramids above are square pyramids.

Cylinders, Cones and Spheres These solids have curved surfaces instead of flat surfaces.
