The volume of a soccer ball is between 332.87 and 371.43 inches cubed. According to Law 2 of the International Federation of Association Football, the soccer ball should be spherical with a circumference between 27 and 28 inches, or 68 and 70 centimeters.
To calculate the volume, first determine the radius from the given circumference. Circumference = pi x 2 x radius. Thus, 28 inches = 3.14 x 2r, with "r" equaling 4.46 inches. Volume = 4/3 x pi x radius cubed, which is equal to 371.43 inches cubed for the ball, if the circumference is 28 inches. For a ball with the circumference of 27 inches, the radius = 27/(3.14 x 2), which is equal to 4.30, and the volume is 332.87 inches cubed.
