No!

You can easily find a counterexample.

Consider a cube of, say, 1 unit length and find it's volume and surface areas.

Then consider a cuboid with sides 2, 1 and 0.5 units long (which has the same volume as the unit cube) and find it's surface area.

You should find that the surfaces areas are different, which dis-proves your statement. - October 19th 2008, 10:56 PMpretzel07
