so it would be 6/3^2 ?

ash2326 · Answer

now we need to find the ratio of volume of small size to the volume of jumbo size.
Could you tell what's the volume of a cube?

anonymous · Answer

the volume of a cube is to the 3 power so the answer should be either A or C right?

ash2326 · Answer

the ratio of volume of small size to the volume of jumbo size.
so the ratio is
$$\large \frac{\text{voulme of small}}{\text{volume of jumbo}}$$
What do you think is the correct option?
