height of one ball is 6.67 (its diameter)
height of 3 balls is therefore 20cm
if you want volume of all 3 balls, that'd be 3(1/6 πd^3)
where d is the diameter.
volume of cylinder is just
πr^2 h = π/4 d^2 h = 3π/4 d^3 = 3π/4 (20/3)^3 = 200π/9
Or maybe something else, since you didn't ask a question.
