Mathematically similar solids? Wow they havent mentioned any more?
anyway volumes will be in the ratios of cubes of a dimension. say x^3/y^3 = 27/125.
=> x/y = (27/125)^(1/3) = 3/5.
Surface areas will be in ratios of squares.
Area1/Area2 = x^2/y^2 = 3^2/5^2 = 9/25.
But its given that Area1 = 36 so
Area2= 36*25/9 = 100cm^2
