Find the volume of a cube whose edge length is 5 cm.

Given:
Cube;
a = 5 cm;
V =?
Decision:
A rectangular parallelepiped, all of whose faces are squares, is called a cube. All edges of a cube are equal. The volume of a cube is expressed by the formula:
V = a³,
where a is the edge of the cube.
Then the volume of a cube with an edge of 5 cm will be equal to:
V = 5³ = 125 (cubic cm)
Answer: 125 cubic meters. cm.
