Find the volume of a cube with an edge equal to 0.3.

A cube is a geometric body, which is a kind of rectangular parallelepiped, in which all faces are square and all edges are equal to each other. The cube consists of 6 faces (equal in area to each other), has 12 edges (equal in length) and 8 vertices.
Designation: V – cube volume, a – cube edge.

Given:
a = 0.3 units.
Find: a.
Decision:
Since a cube is a special case of a rectangular parallelepiped, its volume is also calculated as the product of three dimensions, which are equal for the cube (length = width = height = edge of the cube), therefore: V = a * a * a = a ^ 3.
V = 0.3 ^ 3 = 0.027 (unit ^ 3).
Answer: 0.027 units ^ 3.
