Cube:

It is a six-sided solid figure whose faces are congruent squares, as shown in Figure.

The volume of a cube is computed using the subsequent formula:

V = a3                                                                                

The surface area of a cube is computed using the subsequent formula:

Figure: Cube

SA = 6a2                                                                               

A surface area of a cube is expressed in square units, & the volume of a cube is expressed in cubic units.
