Answer: The similarity ratio of the two cubes is 9 : 15.

Step-by-step explanation: We are to find the similarity ratio of a cube with volume 729 m³ to a cube with volume 3375 m³.

We know that if two solids are similar, then ratio of their volumes is equal to the cube of the ratio of their corresponding sides.

Let, 'a' m and 'b' m be the lengths of two corresponding sides of the cubes with volumes 729 m³ and 3375 m³ respectively.

Then, we must have


729:3375=a^3:b^3\\\\\\\Rightarrow (a^3)/(b^3)=(729)/(3375)\\\\\\\Rightarrow \left((a)/(b)\right)^3=\left((9)/(15)\right)^3\\\\\\\Rightarrow (a)/(b)=(9)/(15)\\\\\\\Rightarrow a:b=9:15.

Thus, the similarity ratio of the two cubes is 9 : 15.
