A standard golf ball has an exact number of dimples on it. how many are they?
The number of dimples on a golf ball varies, depending on the manufacturer and may even be different for different models made by the same manufacturer. The dimples are usually the same size as one another, but some golf balls have several different sizes of dimple on the same ball. Any number between 300 and 500 dimples is reasonable, and 336 is a common number. Not just any number will do.
