Answer 1

Answer:

let the ratio of edges of cube be 3x, 4x, 5x

addition of their volume =

( 3x³) + ( 4x³) + ( 5x³ ) = 27x³ + 64x³ + 125x³

                                  = 216x³

diagonal of combined cube = 12√3

 ∴ side = 12 cm

volume of combined cube = volume of 3 smaller cubes

1728 = 214x³

∴ x = 2

  3x = 6

  4x = 8

  5x = 10

hope it helps...
