Answer: 0.853cm³
Explanation:
Let us assume the density of the uranium alloy to be 18.75g/cm³. If so, then, recall that
Density = mass / volume, so that
Volume = mass / density
We have our mass to be 16kg, and density to be 18.75g/cm³. We will convert the density from g/cm³ to kg/m³, so our density will be, 18750kg/m³, thus, volume would be
Volume = 16 / 18750
Volume = 8.53*10^-4 m³
Volume = 0.853 cm³
In comparison with baseball volume
The baseball is of 7.6cm diameter, so, volume = πd³/6
Volume = π*7.6³/6
Volume = 229.78cm³
Volleyball
The diameter of a volleyball is of average, 21cm, so that
Volume = π*21³/6
Volume = 4749.7cm³
Basketball
The diameter of basketball is, say, 25cm, so that
Volume = π*25³/6
Volume = 8182.3cm³
From the comparison, we can see that the volume of the mass is so small that it is negligible besides a basketball and volleyball. While it is small besides a baseball.
