Find the volume of a cube whose side is 2 cm.

The product of the three main dimensions of a rectangular parallelepiped, that is, length, width and height, determine the volume of the parallelepiped:

V = a * b * c,

Where a, b, c are the length, width and height and they are the edges of the parallelepiped.

A cube is a special case of a parallelepiped, whose faces are equal-sized squares, and the edges a, b and c, respectively, are equal:

a = b = c,

The volume of a cube, like that of a parallelepiped, is equal to the product of the edges corresponding to three dimensions, but since all three dimensions are identical, the volume can be calculated by raising one of the edges to a cube:

V = a * b * c = a ^ 3 = 2 ^ 3 = 2 * 2 * 2 = 8 cm3.

Answer: the volume of a cube with an edge of 2 cm is 8 cm3.
