What is the similarity ratio of two cubes with volumes of 125 cubic meters and 216 cubic meters? Answer 125:216 5:6 25:36 1:3
i think it is 5:6 but im not sure?
You're right, How did you get that?
yes you are right, volume goes with the cube
similarity is alwasys seen in terms of one dimension... for eg. lenght breadth or radius or diameter.. and the volume is 3 dimensional so we find the ratio of the radius and then compare....
ok thank-you!! i forgot how i worked this out it was a few lessons back but i never turned it in so im just checking all my answers before i submit it
By similarity ratio they must mean the length of the side of cube 1 compared to the length of the side of cube 3. They give you the volume of each cube. You know volume = s^3 (side cubed) so find the number so that s*s*s= 125 (s=5) and s*s*s= 216 (s=6) now you take the ratio of their sides to get 5/6
