Weight of Material = 350 lb (350 lb)($\frac{453.59g}{1 lb}$) = 158,756.5 g Volume of Material = 1.2 x 10$^{4}$ in$^{3}$ Volume of Material = (1.2 x 10$^{4}$ in$^{3}$)($\frac{2.54 cm^{3}}{in^{3}}$)($\frac{1 nL}{1 cm^{3}}$) Volume of Material = 196,644.76 mL Density of Material = mass $\div$ volume Density of Material = 158,756.5 g $\div$ 196,644.76 mL = 0.807 $\approx$ 0.8 g/mL As the density of material (0.8 g/mL) is less than the density of the water, the material block will float.
