Area of Cuboid: 2(10×2+10×2+2×2)= 84
Area of each Cube: 6(2×2)= 24
No. of Cubes formed= (10×2×2)/(2×2×2)= 5
So, Surface Area of all cubes= 24×5= 120
So, Ratio of Surface Area= 84:120 = 7:10
(Divide each side by 12)

Sorry......Answer is: 7:10
your answer is wrong it's 11:15
Area of cuboid = 88
88:120 = 11:15
