Volume of cuboid = Area of base x height

                          = 160 x 12 cu cm

                          = 1920 cu cm

New volume after immersion of spheres = 160 x (12+2) cu cm

                                                          = 160 x 14 cu cm

                                                          = 2240 cu cm

Volume of 3 spheres = Change in volume

                              = (2240 – 1920) cu cm

                              = 320 cu cm

Volume of 1 sphere =

Radius of each sphere = 2.94 cm
