Volume of cube is l^3. Surface area is 6l^2. For two cubes of edge length x, y the volumes are in ratio x^3:y^3 and surface areas in the ratio x^2:y^2. Here the ratio of volumes is 10:27 i.e. (³√10)^3:(³√27)^3. Then the ratio of surface areas is (³√10)²:(³√27)². Then you the answer to be ³√100:9

u know i got the same answer but i thought it is wrong
sometimes you get odd kind of answers and it is ok in maths...
