Golf ball

A golf ball comprising a core, an inner cover positioned outside the core, and an outer cover positioned outside the inner cover, wherein

• the golf ball has a plurality of dimples on a surface thereof,
• the golf ball satisfies the following mathematical formulas (III) and (V),
• Sa=4500+10(A−0.5B−2Cs), (III)
• Sa≥4079, and
• 0.04Sa+160−20≤D≤0.04Sa+160+20 (V), where
• A:
• a compression (Atti) of the golf ball,
• B:
• a hardness difference (Shore C) between a surface and a center of the core,
• Cs:
• (Hi×Ti+2Ho×To)/(Ti+2To),
• D:
• a dimple total volume (mm3),
• Hi:
• a hardness (Shore D) of the inner cover,
• Ho:
• a hardness (Shore D) of the outer cover,
• Ti:
• a thickness (mm) of the inner cover, and
• To:
• a thickness (mm) of the outer cover.
