Answer:
[tex]0.0168x^3~g[/tex]
Explanation:
The mass of this iron cube depends on its side length. Assume that the side length of this cube is x. The volume of a cube is then given by:
[tex]V = x^3[/tex]
We know that density is described as a ratio between mass and volume, meaning:
[tex]d = \frac{m}{V}[/tex]
Rearranging this equation for mass, we obtain:
[tex]m = dV[/tex]
Substituting the value of volume and density, we get:
[tex]m = 0.0168~g/cm^3\cdot x^3[/tex]
Based on the value of x, the mass in grams can be obtained using this equation.
