Answer 487.6 cm3
Solution
Length of cuboidal box = 16 cm
Breadth = 8cm
Height = 8 cm
Radius of sphere = 2 cm
                                                                            
                        
                        
The volume of liquid = volume of the cuboidal box – the volume of 16 spheres
