How Do You Find the Perimeter of a Cube?
Finding a perimeter for a cube might seem difficult since perimeters are generally associated with two-dimensional shapes, and a cube is a classic three-dimensional object. A cube, though, can be viewed as a collection of two-dimensional objects, since each of its six faces is a square. Just as the square's perimeter is the sum of its four individual sides, the perimeter of a cube is the total of all of its separate sides, also known as the cube's edges.
