The space occupied by one glass sphere is = 4πr² =(4×22/7 ×2²) =50.28 cm²
then space occupied by 16 spheres is =16×50.28=804.48
then volume of cuboid is l×b×h
then 16×8×8=1024cm³
then substract space of spheres from cuboid then the remaining volume is the volume occupied by water=1024-804.48=219.52 cm³
if answer is not matching then use formula for volume of sphere 4πr³/3 in place of 4πr²
