Homework Help: Math (geometry)

Posted by Emily on Thursday, April 3, 2008 at 11:26pm.

A diagonal of one cube is 2 cm. A diagonal of another cube is 4*sqrt3 cm. The larger cube has volume 64 cubic cm. Find the volume of the smaller cube.
---------------------------------------------------------------------------------------------------

There was this theorem mentioned in the lesson where if the scale factor of two similar solids is a to b, then
1) the ratio of corresponding perimeters is a to b.
2)the ratio of the base areas, of the lateral areas, and of the total areas is a squared to b squared.
3) the ratio of the volumes is a cubed to b cubed.

Does anybody know how to do this? Thanks for all of your help!!
