Homework Help: chem

Posted by Anonymous on Sunday, February 3, 2013 at 5:30pm.

How many pounds does 40.9 in3 of gold weigh? (The density of gold is 19.3 g/cm3, 2.54 cm = 1 in, and 454 g = 1 lb.)

Note these are not large volumes--a cup of water is about 30 in3.

So I tried this question and got 34.73, which isn't right. I used this: (1 in)3 = (2.54 cm)3
Path: in3 --> cm3 --> g --> lbs
can someone help please?
