A material will float on the surface of a liquid if the material has a density less than that of the liquid.

a$.$ Calculate the density of a block of material that has a volume of $2\mathrm{.}40{10}^3$ in$..{?}^3$ and weighs $14\mathrm{.}0lb.$

Density $=$

$\frac{g}{c}{m}^3$

b$.$ Given that the density of water is approximately $1\mathrm{.}0\frac{g}{m}L$ under many conditions, will the block float or sink when placed in a reservoir of water?
