The perimeter of an object is the measurement of the sides of the object. Measuring the perimeter of a square or rectangle is easy, but measuring the perimeter of a cube is slightly more difficult. With a simple measurement, you can quickly calculate the perimeter of a cube.

**Measure the length of one edge of the cube**Each edge of a cube is the same length.

**Count the number of edges of the cube**Every cube has 12 edges.

**Multiply the number of edges by the length of the edge to find the perimeter**For example, if the edge length of a cube is 10 inches, then 10 inches multiplied by 12 edges equals 120 inches.
