depends on what you have in the 740cc's as cc-cubic centimeters is a volume. so if you had 740cc's of air it will weigh a lot less than 740cc's of lead.

If you have 740 ccs of water, you can convert it to lbs by remembering that one cubic centimeter of water weighs one gram. Therefore you have 740 grams of water, which by the miracles of the SI system, is the same as 0.74 kg. Now we can convert one kg to 2.205 lb, so 0.74 kg would be 1.63 lbs.

Just a quick note to add to this. If you visualize what a cc is it may help with the weight issue as well, especially when you are checking your answers.

A cc is also called a ml. These measurements are often used in the world of medicine. If you go to your local hospital or ambulance and ask to borrow a syringe (different sizes), you can see how much volume is in 1 cc by looking at the amount of water needed to fill the syringe to 1cc and so on.

Once you can see this in your minds eye, the calculation should make sense to you.
