The volume of a larger prism is 168 cubic cm. if the prisms are similar with a linear ratio of 3:2 what is the volume of the smaller prism?

How do i figure that out?

Did you learn that the volumes of similar objects are proportional to the cubes of their sides?

so vol(smaller prism)/168 = (3^3)/(2^3)

etc.
