Homework Help: geometry

Posted by Emily on Thursday, April 26, 2007 at 8:49am.

the volume of a larger prism is 128 cubic cm. if the prisms are similar with linear ration of 4:3, what is the volume of the smaller prism?

We have a theorem that says

The volumes of similar objects are proportional to the cubes of their sides.

So let the volume of the smaller prism be V
then V/128 = 3^3 / 4^3
V/128 = 27/64
cross-multiply and solve
