Answer 1

Answer:

Step-by-step explanation:

let edge of cube1 = 3x and edge of cube2 = 2x

1) tsa of cube1 = 6(3x)²

                        = 6 × 9x² = 54x²

    ts of cube2 = 6(2x)²

                        = 6 × 4x² = 24x²

ratio of tsa of cubes = 54x²/24x² = 9 : 4

2) volume of cube1 = (3x)³

                               = 27x³

volume of cube2 = (2x)³

                             = 8x³

ratio between volumes of cubes = 27x³/8x³ = 27 : 8
