cube surface area and volume calculator
a cube is a three-dimensional figure surrounded by 6 identical squares, so it is also called a regular hexahedron and a cube. the english spelling is cube.
cube features
1. the cube has 12 edges, and the length of each edge is equal.
2. a cube has 8 vertices
3. a cube has 6 faces with equal areas.
4. the edge length of the cube is expanded n times, the sum of the edge lengths is expanded n times, the surface area is expanded n² times, and the volume is expanded n³ times.
5. use the same small cubes to make a big cube. at least 8 pieces are needed.
the line ac = cd = db = ab is called a side. each angle (eg endpoints: a, b, c and d) is called a vertex.
each plane such as (abcd plane) is called a face of the cube.
each cube has 6 faces, 8 vertices and 12 sides.
