## hang254 Group Title An aquarium sells cubic fish tanks of different sizes. The length of the small size fish tank is 2 feet. The dimensions of the jumbo size fish tank are double the dimensions of the small size fish tank. Which expression can be used to find the ratio of the volume of the small size fish tank to the volume of the jumbo size fish tank? (2/4)^3 (2/4)^2 (4/2)^3 (4/2)^2 one year ago one year ago

We could try it and find out:

ok, i can see how the proportions between the big fish tank and small fish tank are, but how does one of those expressions act as a proportion ?

Ratio of little to big: $\frac{24}{192}=\frac{1}{8}$

And please not that the ratio of the volumes is the ratio of the sides cubed. So the next time you won't have to draw the picture and figure it out.
