The density of Styrofoam in grams per cubic centimeter is $0.052 \ \frac{g}{cm^3}$ .

The density of the Styrofoam is less than 1, hence it will float in water.

The given parameters;

To find:

1 ounce = 28.35 gram

1 in³ = 16.3871 cm³

The density of Styrofoam in grams per cubic centimeter is calculated as follows;

$\rho = \frac{0.03 \ ounce}{in^3} \times \frac{1 \ in^3}{16.3871 \ cm^3} \times \frac{28.35 \ g}{1 \ ounce} = 0.052 \ \frac{g}{cm^3}$

Since the density of water is $1 \ \frac{g}{cm^3}$ , and the density of the Styrofoam is less than 1, hence the Styrofoam will float in water.
