Question

two cubes have their volume ratio 1:27 the surface area of the cube

Answer 1

Let their sides be a and A

we are given a^3/A^3 = 1/27

                so, a/A = 1/3
      sp, Ratio of surface areas = 6/6(3)^2
                                                = 1:9

Answer 2

ratio of sides = 1:3
TSA of cube 1 = 6.1= 6cm 2
TSA of cube 2  = 6.9= 54cm 2
