The metalloids<span>; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step-like line between metals and non-metals of the </span>periodic table<span>. So there should be 8.</span>
Density is defined as " the ratio of mass of the substance to its volume ". i.e.

8 = 80 / v
It implies that,
v = 80 / 8
v = 10 cm^3
