Solid Geometry is the geometry of three-dimensional space - the kind of space we live in ...

Let us start with some of the simplest shapes:

Cube (Hexahedron)

Cube (Hexahedron) Facts
Notice these interesting things:
	It has 6 Faces
	Each face has 4 edges, and is actually a square
	It has 12 Edges
	It has 8 Vertices (corner points)
	and at each vertex 3 edges meet

And for reference:
	Surface Area = 6 × (Edge Length)²
	Volume = (Edge Length)³

A cube is called a hexahedron because it is a polyhedron that has 6 (hexa-means 6) faces.

Cubes make nice 6-sided dice, because they are regular in shape, and each face is the same size.

In fact, you can make fair dice out of all of the Platonic Solids.

Cuboids, Rectangular Prisms and Cubes

A cuboid is a box-shaped object.

It has six flat sides and all angles are right angles.

And all of its faces are rectangles.

It is also a prism because it has the same cross-section along a length. In fact it is a rectangular prism.
