If the length of the sides of two cubes are in the ratio 4:1, what is the ratio of their total surface area?	Pick:
A) 4:1
B) 6:1
C) 8:1
D) 16:1
E) 64:1
Let x be the length of the small cube's side.   The total surface area of the small cube is 6x^2.   The total surface area of the large cube is 6(4x)^2=96x^2.   The ratio of surface areas is 16:1.   The answer is 16:1.
