To determine the question use Frogs F and G are 5cm to cube and 40cm to cube.
a. Ratio
What are ratio volumes and surface areas for a frog? (The formula for figuring out this data A correlation V square=2/3
Ratio Volumes: Surface areas:
b. Toxin
Let us say that Frog F absorbs 0.015 mL of a certain toxin, then how much would Frog G absorb? mL.
c. Concentration
In order to figure out concentration of a toxin amount for the frog we would divide by the volume. What would the concentration be for frog F and frog G.
Concentration
Frog F:
Frog G:

If F = 5cm^3
G = 40cm^3

then the ratio of volumes is 1:8 = 1:2^3
so the linear ratio is 1:2
so the surface ratio is 1:2^2 = 1:4

If the absorption is proportional to the surface area, then G would absorb 4 times the amount of F.

Since G has 8 times the volume, it would have 1/8 the concentration
