4! = 4x3x2x1 = 24
4x4 = 16
24 - 16 - 4 = 4

If the letter P represents the perimeter, and the letter s is representative of the length of each side, then 4s, or the product of the size length and the number of sizes refers to a square.
To calculate the area of a multi-strand wire you use the formula D = square root of (4S divided by pi), where S equals the number of strands times the area of one strand.
The perimeter is the distance around the square. All four sides of a square are of equal length. The formula for finding the perimeter of a square is P = 4s (the length of one side multiplied by four)
4s (s= the length of one side)
44 - 4 = 40 40 / 4 = 10
