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
