Answer 2

Answer:

Step-by-step explanation:

answer is B )7:9

surface area of cuboid is 2(lb +bh+hl )

so cuboid  surface area is = 2( 12*4+ 4*4+4*12)

                                            =224

total surface area of the  cube  is  6( side  square)

total surface area of the three  cubes  is  6( side  square)+ 6( side  square)+ 6( side  square).

=96+96+96

=288

now ratio of surface area of cuboid and  surface area of three cubes is

=224:288

=7:9
