The perimeter of a cube is simply the perimeter of one side of the cube.

Divide the surface area by six. That will give you the area of one face, which will be a perfect square. The square root of that number will give you the length of a side. The cube of the side will be the volume.

The volume of a 1 inch cube is: one cubic inch.

One cubic unit

If the volume of a cube is 125 cubic cm, the length of each edge is: 5 cm

cube root of volume gives side length, then square this to find area of one face.

-- Measure the length of one edge of the cube (one side of one square face). -- Multiply the number by itself. -- Multiply the result by the original number again. -- The new result is the volume of the cube.

Because a cube is composed of square sides, the edges of each square will be the same length. Therefore if the perimeter of the base is 20 cm, one side would be 5 cm. 4 sides on a square, therefore 20cm/4 = 5 cm. The formula to find the volume of a cube is length x width x height. Like I stated previously, every edge on a cube has the same length. Because of this the length of the cube is equal to the width of the cube and the width of the cube is equal to the height of the cube. Therefore volume of the cube would equal 5cm x 5cm x 5cm, which equals 125 cm. Therefore the volume of a cube that has a perimeter of 20cm for the square base is 125cm cubed.

You would have to specify the shape for which we are finding these quantities. But let us say that it is a cube, which is the easiest. The length of an edge of the cube, multiplied by itself gives the area of a face, and multiplied by itself again gives the volume. So the cube root of the volume is the edge length, and then the square of the edge length is the surface area of one face of the cube, which multiplied by 6 gives the area of the entire cube.
