Answer:
density = 0.16[gr/cm^3] = 160 [kg/m^3]
Step-by-step explanation:
To solve this problem we must use the definition of density which tells us that this is equal to the relationship between mass and volume. In this way we have:
Since the body is a cube, its sides are equal we have:
v = 5 * 5 * 5 = 125 [cm^3]
m = 20 [grams]
density = m / v
density = 20/125
density = 0.16 [grams/cm^3]
Now if we convert the units to the international system, we have:
![0.16[(gr)/(cm^(3) ) ]*(1kg)/(1000gr) *(100^(3) cm^(3) )/(1^(3) m^(3) ) \\= 160 [kg/m^(3) ]](https://img.qammunity.org/2021/formulas/physics/high-school/r6pyha1z506bnf8t44jrpy1mwff6xit2qf.png)
