<span>They are similar because the matter changes in its state...But they are also different because Physical changes have matter that remains the same substance but it is just in a different state and in chemical changes the matter changes completely... Hope this Helps ^-^</span>

Complete Question:
Determine the density of a cube of metal that measures 1.2cm on each side and has a mass of 18.15 grams.
Answer:
Density = 10.706 g/cm³
Explanation:
Given the following data;
Length of cube = 1.2cm
Mass of cube = 18.5g
First we would find the volume of the cube;
Volume of cube = L³
Volume of cube = (1.2)³ or (1.2*12*12)
Volume of cube = 1.728cm³
<em>To find the density;</em>
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
Substituting into the equation, we have;
Density = 10.706 g/cm³
Therefore, the density of the cube of metal is 10.706 g/cm³
