Calcualte your base strength:

$$BaseStrength = Strength * (1 + PotionBonus + PrayerBonus... )$$

Add bonus for combat style using following table:

$$CombatStrength = BaseStrength + CombatStyleBonus$$

Calculate your strength multiplier. You can figure it out by looking at your inventory screen or adding strength bonuses of individual pieces of your equipment together.

$$ StrengthMultiplier = (EquipmentBonus * 0.00175) + 0.1$$

Now you can compute final max hit value: $$MaxHit = floor (CombatStrength * StrengthMultiplier + 1.05)$$
