Question

The density of Styrofoam is 0.03 ounce per cubic inch. What is its density in grams per cubic centimeter? Will it float in water?

Answer 1

To do this, you need to first convert .03 ounces per cubic inch into grams per cubic centimeter by converting ounces to grams and inches to centimeters. There are 2.54 cm in every inch, and there are approximately .035 ounces in a gram. Once you perform these conversions, you should have the density in grams per cubic centimeter that you need. Then, to answer the second question, you need to compare water's density in grams per cubic center to styrofoam's, which you just calculated. If water's is more, then it will float. if not, it will not float. HTH =)
