Answer:
m = 72.9 grams
Step-by-step explanation:
Given that,
The density of a cube, d = 2.7 g/mL
Side of the cube, l = 3 cm
The volume of the cube is :
[tex]V=l^3\\\\V=(3)^3\ cm^3\\\\V=27\ cm^3[/tex]
Since, 1 mL = 1 cm³
Mass per unit volume is equal to the density of an object.
[tex]m=d\times V\\\\m=2.7\ g/mL\times 27\ mL\\\\m=72.9\ g[/tex]
So, the mass of the cube is 72.9 grams.
