性的秘密（The secret of sexual） 1. The number of copies per share = total number of copies = total number of copies = number of copies = number of copies = every number of shares 1 multiple times = multiples of multiple times = 1 3. Time = distance = time = time = time = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = speed = time = The unit price is equal to the total price of the total price Work hours = work hours = total amount of work = work time = total amount of work Working hours = work efficiency 6, + + + + + = and -one addition = another plus 7, the number of subtraction = difference = difference = the minus, the minus, the minus, the minus 8, the factor x factor is equal to one factor = another factor 9. The number of divisor is equal to the quotient (quotient) 1, square: C perimeter S area a, perimeter = side length x 4 C = 4a area = side length x side length S = a * a (2) cube: volume a: the surface area of the edge is equal to the length of the rib (x) x 6 S The volume is equal to the length of the edge x 3. Rectangle The circumference of C perimeter S is equal to the length of a side and the circumference of a side is equal to 2 (a plus b), which is equal to the length x width S = ab cuboid V: volume s: area a: long b: wide h: high (1) surface area (length x width + length x height + wide x height) * 2 S = 2 (ab + ah + bh) (2) the volume = long * width/high V = abh 5. Triangles The area of s is the height of h Triangle height = area x 2 The base of the triangle = area * 2 is high 6. Parallelogram: the area of s is the area of a base h = base x height s = ah The height of the bottom of the bottom b is equal to the height of the bottom and the bottom of the top 8 circle: S area C perimeter pie d = diameter r = radius (1) circumference = diameter x = 2 x = 2 x radius C = 2 r (2) area = radius x radius (x) Cylinder: v volume h: the radius of the base area r of the high s is the cir
