Answer:
density of cube =11.605 g/cm³
Explanation:
density of a substance is the mass per unit volume of that substance.
the density of a substance = [tex]\frac{mass}{volume}[/tex]
volume of a cube = l³,
l = 19.0mm , lets convert mm to cm
1mm = 0.1cm, thus, 19mm =19*0.1 =1.9cm
length of cube =1.9cm
volume of cube = 1.9³
density of cube = [tex]\frac{79.6}{1.9^{3} }[/tex]
density of cube =11.605 g/cm³
