A parallelepiped rectangle with all congruent edges (a = b = c) is named cube. This way, the six faces are square.

## Base and cube diagonals

Consider the following figure:

d_{ç}= cube diagonal

d_{B} = base diagonal

In the ABCD base, we have:

In the ACE triangle we have:

## Side area

The lateral area **THE _{L}**is given by the area of the side squares

**The**:

THE_{L}= 4th^{2} |

## Total area

The total area **THE _{T}**is given by the area of the six side squares

**The**:

THE_{T}= 6a^{2} |

## Volume

Similar to the rectangle parallelepiped, the volume of an edge cube **The** It is given by:

**V = a. The . a = a ^{3}**
