#91.8 cm^3#

Explanation:

Volume of the box is #12.1 xx 3.5 xx 3.5=148.225 cm^3#

Each ball is #4/3 xx pi xx 1.65^3=18.8165692 cm^3#

There are three balls #=> 56.4497076 cm^3#

Subtract

#=> 148.225-56.4497076=91.7752924 cm^3#

#V_"empty space"=91.775# #cm^3#

Explanation:

#V_"box"=l*w*h=12.1*3.5*3.5= 148.225# #cm^3#

#V_"each ball"=4/3pir^3=4/3pi(3.3/2)^3=4/3pi(35.937/8)# #cm^3#

#V_"3 balls"=(35.937/2)pi~~56.450# #cm^3#

#V_"empty space"=148.225-56.450=91.775# #cm^3#
