If you have ever seen a cube, you may wonder how many edges does it have? A cube has eight vertices. Each vertex has three sides that meet with three edges. The angles between the faces are right angles.
The edge of a cube is the boundary that joins the vertices. Edges are also used to describe 2d shapes. It can be easier to count straight lines when you know the number of edges.
In addition to the edges, there are six square faces. There are four equal sides on each face. Two of the faces are parallel. These are called the space diagonals. They cut through the interior of the cube.
Another way to visualize a cube is as a square prism. As with a hexagon, the edges are parallel. On the horizon, the corner of the cube is a hexagon. When you see a cube from the side, it's a square.
Cubes have the largest volume of all the cuboids with the same surface area. Unlike other cuboids, the volume of a cube is the third power of the sides. That's s3.
Using the same formula, you can calculate the length of a space diagonal. For a square, the length is s. So the total length of a cube is s3.
A cube is also one of the only Platonic solids with point symmetry. This is a specialized form of geometrical symmetry. You can also call the cube a regular hexahedron.
