The density of Styrofoam in grams per cubic centimeter is
.
The density of the Styrofoam is less than 1, hence it will float in water.
<u />
<u>The given parameters;</u>
- density of Styrofoam = 0.03 ounce per cubic inch
<u>To find:</u>
- the density in grams per cubic centimeter
1 ounce = 28.35 gram
1 in³ = 16.3871 cm³
The density of Styrofoam in grams per cubic centimeter is calculated as follows;
![\rho = \frac{0.03 \ ounce}{in^3} \times \frac{1 \ in^3}{16.3871 \ cm^3} \times \frac{28.35 \ g}{1 \ ounce} = 0.052 \ \frac{g}{cm^3}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7B0.03%20%5C%20ounce%7D%7Bin%5E3%7D%20%5Ctimes%20%5Cfrac%7B1%20%5C%20in%5E3%7D%7B16.3871%20%5C%20cm%5E3%7D%20%5Ctimes%20%5Cfrac%7B28.35%20%5C%20g%7D%7B1%20%5C%20ounce%7D%20%3D%200.052%20%5C%20%5Cfrac%7Bg%7D%7Bcm%5E3%7D)
Since the density of water is
, and the density of the Styrofoam is less than 1, hence the Styrofoam will float in water.
